Looks like an infanite loop. But why in the middle of the board?
When I move my tetris shaped block it moves fine untill I get near the middle of the screen, then the CPU goes MAXed out. (Looks like an infanite loop. But I am not sure. And even if it was. Why in the middle?)
Sorry for the long script, but I don't know where the problem is.
Code:
