BOOMPLANE

What it is

BOOMPLANE is a vertical shooter you fly with one finger. The world's finest aviation workshop (self-declared) has exactly one plane left: JUNK-1, with crooked wings and a smoking engine. There are no working planes, so it has to fly. Drag anywhere on the screen and the plane follows; the weapons fire on their own. Every part the enemy drops makes it stronger. Nobody knows why. The game is in English.

Problem it solves

Shooters tend to put all your attention on dodging, and once the weapons are fully grown the same scene plays over and over. BOOMPLANE puts smashing ahead of dodging. A screen packed with enemies blows up all at once, again and again, so a run leaves you feeling lighter. It is not a game you can sit still in, though. Red shots your guns cannot stop, junk falling right where you fly and fighters climbing up from below keep you moving. Even after your weapons are fully grown, there is always something left to pick and another rank to climb.

Core loop

• A run lasts from takeoff until you crash. Each zone takes about three minutes and ends with a boss. Beat the boss and you fly straight into the next zone, with no menu to pick from and no button to press.
• The zones go JUNKYARD SKY, CLOUD CHAOS, SPACE GARBAGE, then around again with the threat level (THREAT) one higher. There is no end.
• Three hearts that never grow. Every hit costs a heart, and every zone you clear fills one back.
• Beat a boss and the zone's report card rolls in: enemies destroyed, best combo, hits taken and time, a rank from S to C and bonus screws. Clear a zone without a hit for an extra FLAWLESS reward.
• When you crash, you keep every screw from the run. ONE MORE on the result screen sends you straight back up.

Main features

• From scrap to a flying fortress: parts grow the machine gun from one shot to a five-way spray. Weapon capsules bring homing missiles, a piercing laser, helper drones, spinning buzz saws, a chain-lightning zapper and fireworks rockets. Every weapon bolts onto the plane.
• Pick by flying: capsules come in pairs, and only the one you fly into is fitted. Four weapon slots besides the machine gun mean the plane grows differently every run. The fight never pauses while you choose.
• Evolutions and upgrades that never end: every weapon has an evolved form (GATLING HELL, MISSILE PARTY, MEGA BEAM, DRONE SQUAD, SAW STORM, THUNDER CLOUD, GRAND FINALE). After it evolves, every capsule of that weapon adds a star, and every third star brings a new tier: MEGA, ULTRA, HYPER, OMEGA and beyond. Ten kinds of perk cards turn up among the capsules and make a different build every run.
• Transform: fill the bar at the bottom and the plane transforms mid-fight into MK-2, MK-3 and on, with a shockwave that flattens everything around it. Fill it again and it transforms again, with no end.
• Bombs: grab bomb crates to fill your bag (three to start). A throw sweeps away the enemy shots around you, then the bomb blows up a crowd ahead, cracks armored safes and dents bosses. Press BOMB, double-tap anywhere or tap with a second finger while you drag.
• Satisfying chaos: swarms of dozens of tiny fighters, BOOM FEVER (eight seconds of every weapon you have at full blast, with chain explosions everywhere) and BOOM!, KABOOM!, MEGA BOOM! when you wreck a crowd within one second.
• Twenty-one kinds of enemies and three bosses: angry fans, flying fridges, toasters that pop out angry toast, a vacuum cleaner that steals your drops, desk lamps that fire beams, charging kettles, an alarm clock that makes everyone angry and more. The bosses are the MEGA FAN, the FRIDGE 3000 and the TRASH KING, and each one rages and speeds up as it breaks. Every big attack shows a red warning first.
• Zone events: three times a zone, something shakes up the fight: a GOLD RUSH of runaway piggy banks, a LOOT BLIMP, BOOST RINGS, a BALLOON PARTY, a METEOR STORM or a SUPPLY DROP.
• Daredevil and power-ups: fly in the top half of the screen, closer to danger, for double screws. Eight power-ups, from COFFEE BREAK (double fire rate) to SUPER SIZE, TURBO STAR, MAGNET STORM, FREEZE RAY, DOUBLE SCREWS, SPARE PARTS and BUBBLE.
• Growing between runs: spend screws in the GARAGE on attack, repair kits and magnet range, 30 levels each. Three daily missions, a daily bonus that grows every day in a row, achievements and records to beat.

Product decisions

• The fight never stops. Every upgrade comes from picking up the parts and capsules enemies drop. There is no card screen when you level up and no slow motion.
• Every dangerous attack is shown first: warning lines for beams, target circles where junk will fall and arrows for attacks from below. Read them and dodge, destroy the source first or clear them with a bomb. Even the bosses have no instant-kill attacks.
• Upgrades are seen and heard before they are counted. Each weapon bolts a part onto the plane, an evolution flashes gold and each tier changes the color.
• Enemies grow a lot with every zone while your power adds up a little at a time, so every run ends eventually. How far you got is the record.
• Planes and flight items opened with an ad last one run. There are no paid items, loot boxes or pay-only weapons.

Pricing

Free, with no in-app purchases and no banner ads. The starting plane JUNK-1 plays the whole game. On Android you can choose to watch a rewarded ad to arm a new plane or a flight item for your next run only, to keep flying once after you crash or to double the screws of a finished run. One full-screen ad appears when you leave the result screen after every second finished run, never during a flight. The game plays offline.

Next hypotheses

Measure which zone players crash in and how long a run lasts, then tune how fast enemies grow from zone to zone and how often the full-screen ad appears.
