Someone said Choppaaaaaaaaaaaaaaaaaaa-aaah never mind, that joke's getting old :). In short: it's a monochrome physics game where you get to fly a cute chopper around caverns and reach the levels' designated points. It's visual style is nice, with texts mocking the game itself spread across the levels (which act like a tutorial too). The music score is unusual for games like these, but very fitting and fun.
Give it a go, I'm sure you'll find it difficult to stop after you play a couple of levels :)
