Good fun
It was good fun for quite a long time.
Would be nice to see more upgrades or whatever, and also make the game screen larger so players can see obstacles sooner, because at high speeds sometimes obstacles are simply unavoidable. That, or add in a radar or something. Apart from that, the game is quite nice and the music is pretty well done as well. My only other concern is the high-scores submission; I got 4000+ scores quite a few times, submitted them, but they never showed up. :P
