App Info

App Name	Cometdive
Version	1.0.0
Developer	Willee Project
Platform	Android

Cometdive is a vertical arcade space shooter you play with one hand. Drag left or right anywhere on the screen to move your ship; it fires on its own. Enemies fly in as formations and dive at you. Catch the divers to fill the comet gauge, then your ship becomes a comet and pierces straight through the formation (the Comet Dive).

• There is no sign-up and no login. The first time you open the app, a tutorial on a practice sector teaches the controls and the Comet Dive. You can end it at any time with Skip, and replay it from Settings.
• The game works without an internet connection. The internet is only used for ads and for sending usage statistics and crash reports.
• The app follows your device language. It supports English, Korean, Japanese and Chinese (Simplified and Traditional), and you can also pick a language in Settings.

1. Rules

• A sector is three waves and a boss. Destroy every enemy in a wave to move on to the next, and the boss arrives after the third wave. Defeat the boss to clear the sector. A sector takes about three minutes.
• You start every sector with three ships. A hit costs you a ship and gives you a moment of invulnerability. Lose all three and the sector is failed. There are no continues. A shield absorbs a hit without losing a ship (from cards and from the Hangar's Hull branch).
• Enemies give you points. A diving enemy is worth double and fills the comet gauge more.
• Combo: destroy another enemy within about 1.2 seconds of the last one and the combo goes up by one (to a maximum of ×8). Your combo multiplies the points of each kill. Let the time run out and it drops back to ×1.
• Bonus points are added when you finish a wave and when you clear a sector. The bonus grows with the number of enemies you destroyed with the Comet Dive, and with a No-hit clear, a clear in which you were never hit.
• Clearing a sector unlocks the next one (chapters 3 and 6).
• A run in progress is not saved. If you leave to Home, that sector starts over.

Reading the play screen

• Top bar: your score (eight digits), SECTOR and WAVE, COMBO with a bar for the time you have left to continue it, and the pause button. When a boss appears, its health frame shows up, and a WARNING strip flashes just before it arrives.
• Under the board: your remaining ships and the COMET gauge (10 cells). READY lights when the gauge is full.
• The rounded pad at the very bottom is the control strip (chapter 2).

2. Controls

• Drag: touch anywhere on the screen and drag left or right, and the ship moves by as much as you drag. Your finger does not have to be on the ship, and the ship only moves left and right along the bottom of the screen.
• The control strip below the board: dragging on it works the same way, and your finger never covers the ship. The ‹ or › on the side you drag toward lights up, and the whole strip glows orange when the gauge is full.
• Your ship fires on its own. Get under the enemies and hit them.
• Pause: tap the pause button on the top bar. Pressing Back, or sending the app to the background, also pauses. The pause window offers Resume, Restart (this sector from the beginning), Settings and Home. Anything you change in Settings from there applies to the run at once.
• Drag sensitivity is fixed and is not a setting. Upgrading the engine in the Hangar raises it together with your move speed (chapter 7).

3. Comet Dive

• Destroying enemies fills the COMET gauge: a little for enemies holding formation, a lot for diving ones. When all 10 cells are full, READY lights up and the control strip glows orange.
• With a full gauge, start the Comet Dive in one of two ways.
  • Flick up: flick your finger up the screen fast (↑ Flick up: Comet Dive).
  • Tap the strip: tap anywhere on the control strip and lift (Or tap the strip below). A long press or a drag does not trigger it.
• For about 0.8 seconds your ship surges up the screen as a comet and pierces the enemies in its path. When the gauge is full, the dive lane (chevrons) and rings around the enemies in it are shown. You can still drag left and right during the dive to bend your path a little.
• The dive breaks through enemies wearing a ring shield and also damages bosses. It cannot break a beam. The dive uses up the gauge, so you fill it again.
• The number of enemies you destroyed with the Comet Dive is shown in the result and in Records, and counts toward the sector clear bonus.
• During play, a hint appears for your first few dives to remind you how.

4. Cards

• After each wave you pick one of three cards (Wave N clear · Choose a card). Cards stack only within that sector, and the next sector starts over from nothing.
• Picking the same card again raises it to level 2. Some cards have only one level.
• You begin with ten kinds of cards, and the rest join the pool one at a time as the zones go up (the Zone column in the table).

Card	Effect
Multi-shot	Fire two parallel shots → three
Spread shot	Add an angled pair of shots → two angled pairs
Rapid fire	Less time between shots (up to 3 times)
Piercing shot	Shots go through one enemy → two
Homing missiles	Fire missiles that chase the nearest enemy → more often
Wing drone	A drone fires beside you → two drones
Shield	One shield: take a hit without losing a ship → one more (refills all when chosen)
Comet charge	The comet gauge fills faster → much faster
Dive warning	Enemies flash orange before they dive
Extra ship	One more ship in reserve
Side guns (from Zone 2)	Your wingtips fire angled shots → more often
Heavy rounds (Zone 3)	Every 4th volley, straight shots deal double damage → every 3rd
Combo keeper (Zone 4)	Combos last longer, raising your score → much longer
Dive hunter (Zone 5)	Double damage to diving enemies → diving kills also fill the comet gauge faster
Chain arc (Zone 6)	Kills arc to one nearby enemy → two
Comet nova (Zone 7)	Your Comet Dive bursts a shockwave near the top → a second shockwave where you land clears nearby shots
Pulse laser (Zone 8)	Fires a piercing laser upward at intervals → more often
Comet wake (Zone 9)	Your Comet Dive leaves embers that burn enemies → the embers last longer

• Upgrading the Hangar's Tactics branch helps you use cards. You choose a card before wave 1 (Choose a card before launch), you can Reroll the choices (1 to 3 times per sector, with the Reroll (N left) button on the card screen), and later you choose from four cards (chapter 7).

5. Enemies, obstacles and bosses

You can look at all of these again in the Codex (chapter 8). When a sector brings a new enemy or boss you have not met, an introduction card appears at the start.

Enemies and tiers

There are 16 enemy families. As the zones go up, higher tiers of the same family appear. A higher tier is tougher, and tier 4 has one more attack. Tiers are told apart by body color and white stripes.

Name	What it does
Quark	The backbone of the formation. Fires now and then, and once while diving.
Starray	Curls and dives fast, firing twice on the way down.
Oort	Hard to crack. Sprays a fan of needles as it dives.
Cluster	Sturdy. Releases two Neutrinos when first hit.
Gamma	Takes precise aim at you with needles from the formation.
Neutrino	Released by Clusters and bosses. Swoops straight down.
Solar Sail	Zigzags down and drops a shot at every turn.
Plasma Lance	Pauses mid-dive, then spears straight down its lane.
Meteor Gun	Heats its barrels, then fires big, slow shells.
Lagrange	Sways as it sinks and drops two shots side by side.
Swingby	Fires hook shots that turn down and narrow your path.
Eclipse	Swoops halfway down, fires, and returns to its place.
Stardust	Crosses the field and leaves mines behind.
Quadrant	Spins down and scatters four shots in an X.
Sun Lens	Draws a warning line, then drops a beam along it.
Aurora	Wraps the enemy below it in a barrier. Take it out first.

Elites

Elites are stronger enemies that carry a marker.

Name	What it does
Ringshield	Wears a ring that blocks two shots. A Comet Dive breaks through.
Bounty	Big score and comet gauge if you catch it. It flees after one dive.
Prowplate	Shrugs off your shots in formation. Hit it while it dives.
Overdrive	Dives faster and more often.
Splitter	Bursts into two Neutrinos when destroyed.
Minetail	Leaves a mine where it was destroyed.

Obstacles

Name	What it does
Driftrock	A slow-falling rock. Break it and it splits into two pebbles.
Volatile crystal	Shoot it to burst and wreck the enemies around it.
Wreck	Unbreakable debris that blocks shots from both sides.
Meteor shower	After a warning, small meteors pour down in one line.
Gravity well	A vortex that bends your shots toward its center.
Arc pylons	Their current blocks your shots. Destroy one to cut it.

Enemy shots

Enemy shots are told apart by shape and glow, not by color alone.

Name	What it does
Orb	Round and slow. The most common enemy shot.
Needle	Thin and fast. Often comes in a fan.
Shell	Big and slow. It narrows your room to dodge.
Hook	Turns once at a set moment.
Mine	Stops, blinks, and bursts into a ring. Two shots put it out.
Beam	A pillar of light that strikes along the warning line. Your Comet Dive can't break it.

Warnings before dangerous attacks

Dangerous attacks show a warning from the moment they begin. A beam draws a warning line first, a mine blinks before it bursts, a meteor shower pours down after a warning, and a bullet curtain shows its gap as an open lane. A WARNING strip appears when a boss arrives. The Dive warning card makes enemies flash orange before they dive.

Bosses

Every sector ends with a boss. At the last sector of a zone you meet a new boss or a boss in its second form (the name followed by II), and the second form attacks differently.

Boss	What it does	Second form (II)
Titan	Aims from its twin turrets and bursts rings and spirals from its hull.	Its turret covers blow off to bare three barrels. It shifts and drops bullet curtains with a gap.
Nebula	Aims fans of needles from its wing cannons and bursts rings and spirals.	Spreads its fins and lunges, then its wing cannons sweep fans of shots across each other.
Prism	Its two crystal shards fire needle rings while its body spins spirals.	Its blades split and its shards circle it, then it raises fences of beams.
Star Furnace	Aims shells from its exhaust guns and drops bullet curtains with a gap.	Its grate bursts open and spills fire. It lunges, drops bullet curtains, and scatters mines.
Orrery	Four orbiting spheres fire outward, and fans of hook shots turn toward you.	Its rings tilt and its spheres speed up. It sows mines and fires turning shots.
Ion Spire	Raises fences of beams and sweeps the field from its two capacitors.	Lightning wraps its coil. It raises staggered beam fences and bullet curtains, and calls Swingbys.

6. Modes

Home

The top has the title and the home-screen visuals, and the gear-shaped Settings button is at the top right. Below are two large buttons and three small ones.

Button	What it does
Start sector N	Starts the furthest sector you have unlocked, with its boss and your best score for it shown.
Daily	Starts today's Daily. It shows today's boss, and if you have finished a run today, today's best and your streak.
Sectors	Pick any unlocked sector (below). It shows your current zone number.
Hangar	Spend cores to upgrade your ship (chapter 7). It shows your core balance, and a dot appears when you can afford an upgrade.
Records	Opens your records and the Codex (chapter 8). It shows your highest sector.

Classic

• Eight sectors make a zone. Zone 1 is sectors 1 to 8, and from sector 9 the sectors keep coming with no end (Zone 2, Zone 3, and so on).
• Clearing a sector unlocks the next one. You can replay any unlocked sector at any time, and your best score is kept. A sector you have not unlocked is Locked: Clear the previous sector to open it.
• The last sector of a zone (the eighth) is where a new boss, or a boss in its second form, waits. Clear it and Zone N cleared appears.
• The score multiplier rises with every zone, up to ×3. Your record centers on the highest sector you have reached.
• Hangar upgrades you have bought take effect in Classic (chapter 7).

Sectors

• Each zone is one page, and you swipe up and down to turn between them (the earlier zone is below, the next one above). At first you see the zone with the sector you are due to play, and you can only swipe as far as that zone.
• A page is a route that zigzags upward, with a hexagonal tile for every sector showing its boss (the zone's last tile is larger). The boss of a sector you have not unlocked is hidden behind a ?. Your ship hovers over the sector to play next.
• The label outside each tile shows the sector number, two medal slots (Clear and No-hit clear), and your best score (New if you have none, Locked if it is not open yet).
• The zone name, sector range and number of sectors cleared are in the top corner of the map, and the thin line along the right edge shows where the current zone sits.
• Tap an unlocked tile to start that sector. Tap a locked one to be told how to open it.

Result screen

When a sector ends, the result counts up. You see Score, Best score (New best if you beat it), Hits, Comet Dive kills, Time, and three medal slots (Clear, No-hit clear, Comet ×N). On a clear, Sector N unlocked appears, and the cores you earned are shown (First clear +N, Zone finale first clear +N). If you can afford an upgrade, N upgrades ready and a Hangar button appear. The buttons are Next sector (after a clear), Restart and Home.

Daily

• One sector opens each day. The date is your device's date, and a new day begins at midnight.
• On the same day, players who meet the same boss get the same waves and the same card choices. The boss is chosen day by day from the bosses you have met so far, so a boss you have not met never shows up in Daily (if you have met none, it is the first boss, Titan). Bosses never appear in their second form in Daily. The day's boss is fixed the first time you look at it and does not change that day, and a boss you meet newly joins the rotation from the next day.
• In Daily, everyone flies the same ship, without Hangar upgrades. The start card says STANDARD.
• You can play it more than once a day, and your best score of the day is kept.
• A day on which you finish a run (cleared or failed) extends your streak, and missing a day breaks it. The streak shows in Records, on the Daily button on Home, and on the result screen.
• Daily earns cores too: cores for your score, plus a bonus for your first finish of the day (Today's first finish +N).

7. Hangar

The Hangar is where you spend the cores you earn in play to upgrade your ship. Open it from Hangar on Home or from the Hangar button on the result screen. There is no banner on this screen.

Earning cores

• In both Classic and Daily, every finished run earns cores equal to your score ÷ 2,000 (rounded down), cleared or not.
• You earn 50 more the first time you clear a sector, 200 more the first time you clear the last sector of a zone, and 50 more for your first finish of the day in Daily.
• Cores come only from play. They cannot be bought in the app.

Upgrades

• There are five branches and 35 steps in all. The top bar shows your core balance, the ship panel shows your current form, below it are five branch rows (step cells, a "now → next" effect line and a price button), and at the bottom is Launch · Sector N.
• Tap a price button once and it turns into Confirm N for 2 seconds. Tap again to buy. If you are short of cores the button is dim and you cannot buy. There are no refunds.
• Effects are shown as simple numbers, like "Fire rate 1 → 2". A note appears the first time you visit.

Branch	Steps	What goes up
Main gun	10	Fire rate, shot size, shot damage
Comet	10	Starting gauge, dive width, dive damage to bosses
Engine	5	Move speed
Hull	5	Starting shield, refill one empty shield before the boss, a breaking shield clears nearby enemy shots (and clears a wider area)
Tactics	5	Choose a card before wave 1, rerolls per sector (1 to 3), choose from four cards

• On the Engine row, Move speed in play ‹ › lets you lower the move speed used in play, among the steps you have bought, if the ship feels too fast.
• Steps get more expensive as they go up, and buying all of them takes about 164,000 cores.
• Hangar upgrades work only in Classic. Daily and the tutorial always use the same basic ship.

Ship forms

As your total steps grow, your ship changes form through ten of them: MK I (Spark), MK II (Flare), MK III (Blaze), MK IV (Inferno), MK V (Supernova), MK VI (Pulsar), MK VII (Magnetar), MK VIII (Quasar), MK IX (Hypernova) and MK X (Big Bang). It changes at 3, 7, 12, 19, 23, 26, 29, 32 and 35 total steps. A form changes how the ship looks; its strength comes from the upgrades you have bought. When it changes, a short effect plays and From your next launch: MK N appears.

• The form row shows a picture for each form you have reached and a silhouette for those you have not. Tap a reached form to look at that ship (Now flying: MK N stays the same). It is view-only, and the ship you fly does not change.
• The ship panel shows how far it is to the next form (N more upgrades to the next form, or Final form at the end).

8. Records and Codex

Open them from Records on Home.

• Highest sector (the big number), Sectors cleared, No-hit clears, Best score
• Zone Records: tap it to see the records of every zone (each zone's eight sectors with their bosses and best scores).
• Daily: Current streak, Longest streak, Today's best, Best ever, Days played
• Totals: Play time, Runs, Clears, No-hit clears, Enemies destroyed, Comet Dive kills, Comet Dives, Best combo, Bosses destroyed, Ships lost
• Codex: enemies, elites, bosses, obstacles, cards and enemy shots make 109 entries in all. Each category shows the most recent entry you found, Found N/M and a progress bar, and tapping a category lets you browse its entries. Entries fill in when you first meet them in play, and ones you have not met yet show as silhouettes marked Not found yet. The Ship forms section fills in with the forms you have reached in the Hangar.

10. Ads and where your records are kept

• There are no ads and no purchases during play. The play screen, card choice, pause, the tutorial, the result screen and the Hangar have no ads.
• A banner ad sits at the very bottom of Home, Sectors and Records.
• A full-screen ad can appear only after you tap a next action on the result screen (Next sector, Restart, Home and so on), and only now and then. It can appear once you have played 20 minutes (only time spent in a run counts, not menus or pauses), and after that you must play another 15 minutes after the last ad before one can appear again. None appears after the result of the first run since you opened the app, after a Restart right after a failed run, or after the tutorial.
• In regions where consent is required (such as Europe), an ad consent screen appears. You can change it later in Settings under Privacy options.
• There is nothing to buy in the app.
• The internet is only used for ads and for usage statistics and crash reports.
• Your records and settings are stored on your device. If your device's Google backup (Android Auto Backup) is on, they are included in the backup, so you can carry on after changing devices. Deleting the app also deletes the records on the device.
• For details, see the Privacy policy.
