Bullet Eater

A shoot 'em up in which enemies' bullets heal you instead of hurt you. Your health bar gradually decreases over time, so you have to keep eating bullets to stay alive.

There are 6 stages. Each stage has a hidden CD you can find, which lets you listen to that stage's music in the main menu. There's also Time Attack and Score Attack modes, each with 6 unique courses (but you have to unlock them first).

Controls:
Mouse - Move
Left-click - Shoot
Right-click - Boost (makes the screen scroll faster, but your health decreases twice as fast)
Space bar / Enter - Pause
