Great music, nice gameplay and good controls!
Like others have mentioned, there are cases where asteroids spawn on top of your ship which I feel detracts from the game-play experience, but overall a solid game concept. If fleshed out, it could be really fun to play and maybe very popular!
Another thing I wanted to mention is that I feel this game doesn't follow the "one-button" rule set out in the jam specification. But I've only been playing on computer, so it might work differently on mobile: and, technically, since the game only uses mouse movements on computers, it doesn't use more than one button!
Very nicely done.
