First of all, the Linux version (x86_64) didn’t start for me (I attached a screenshot of the error). The Windows version worked just fine under the emulator, though :)
An interesting game, loved the idea! Had the feeling that using long-range ships is the way to go, you can’t really destroy all the asteroids in time with a short-range gun (or at least I couldn’t :D). Precise aiming at small asteroids with a long-range gun is a little hard, since a single key press moves the gun at quite a large angle; not sure how this can be solved, though. Rotating asteroids are a really nice touch - they look like they’re moving faster but they actually aren’t. Got to 48% only, though. Still, a fun game, enjoyed it!
