Hi!
Game looks really good. Only font is a bit unreadable.
But i found some bugs
:
-i can't start a new game with AI after finishing one. Looks like you don't reset level.
-when i choose play vs human, the humancontrols screen appear and it say "press any key to continue" but when i press any key, nothing happen. Only when i press enter im back to menu. This problem appear after i finish a game with AI so it could be connected with first problem
-not a bug but: ball is not center at the start.
-not a bug again but: ball always go in same direction after start
-collisions looks weird
-when point go to 10 number overlay on middle line
After all, game looks good, i like that GUI system. But you need to work more with it. Not much, but still a bit. Good work!
