well...
couple things, remake and resubmitt and i think it could be good.
1. music was horrendous. drove me crazy where i just quit.
2. didnt like the fading ball
3. the ball was able to pass through the corners of the walls atleast the length of the ball, so you might want to fix that
other then that i liked it. i have falldown on my calculator and i play it all the time, its great
