In each of the 5 levels, you have to fire the ball so that it crosses the pink line. It can bounce off the yellow and red lines, but you only have 30 seconds to complete each level. The score you get is related to how much time you have remaining. On each level you can have as many attemps as you like (within 30 seconds). If the ball gets stuck, you can reset it.
Mouse - (aim)
Spacebar - (fire)
Z - (reset ball)
