Squadrons of boner killers sweep through on flight paths - shoot them down before they escape, and dodge everything they throw back. Every fourth wave Performance Anxiety rolls in as a boss. You start with 3 lives.

Keyboard

Arrow keys (or WASD) fly in every direction. Space shoots - hold it for autofire. Shift barrel-rolls: a moment of invincibility, 3 per life. P pauses, M toggles sound.

Touch

Drag anywhere on the field to fly - the ship follows your finger's movement, not its position, so your thumb never covers the action. Hold the fire button to shoot; the gold button above it barrel-rolls. The arrows button swaps which side they sit on.

Worth knowing

Hits build your score multiplier up to x8 and misses shrink it, so don't spray. Wipe a whole green pager-cock squadron before it escapes for a bounty and a guaranteed drop: coffee upgrades your gun, an oyster adds spread shots, a wing-cock joins your flank and soaks one hit for you, and the blue pill makes you big and briefly invincible. Near-miss shots pay a graze bonus. From wave 20 coffee keeps climbing past triple, to a quad gun and then piercing wads, and a gun that has climbed past triple never drops below it when you die. Performance Anxiety takes double damage down the throat: line up with the middle of the cloud.
