Regarding the game itself: since the reflection angle is strictly determined, instead of varying with the place of reflection, the ball path seems to be is fully determined by the initial position and angle of the ball launch (aside from a paddle miss, of course). Specifically, a situation is possible where you bounce the ball in a cyclic path that doesn't strike the last block(s).
