The game's pretty fun, if disorientating :D Sometimes you can't see any asteroid on screen so you have to make a leap of faith and potentially go too far. It would probably also make the game easier if you could split the "jumped in the right direction" indicator into X and Y axes. Having to make long jumps *and* only getting a small hint as to whether you've chosen correctly is a bit much, I feel.
Other than that, I really liked the game and the graphics. I found the sounds and music to match well. Good job! :D
I made it with just 3% oxygen left :D
