It's a simple but good concept, and the art works great with it :)

The music is nice initially but it quickly becomes repetitive, especially since the game does not increase in difficulty so if you're good at it, you can just go on forever (I left myself explode after passing 200 meteorites as it was getting boring :D). It would be nice if the difficulty (speed) increased progressively, and the music too (with more variations on the base motif).

Please properly export you game as well in addition to only distributing the source-code  :p

I know you might not want to publish untested builds, but linux users would appreciate them.
