I like the graphics (especially the motion trail), the music, and the physics. I'm confused, though, why did you choose Up/Down for the controls instead of Left/Right? I think that would have made a lot more sense and still kept the interesting part of the challenge -- actually navigating the course. Overall, though, nice job!
B0LL0X is a ball racing game.
ARROW KEYS UP & DOWN to move
ENTER to start
In the title screen there is a pratice track to familiarize with the controls, when you are ready press enter.
Remember: complete the track in less than 20 seconds.
