I liked the music, it fit the gameplay well. Nice particle effects on the win screen! :) The game is pretty simple but fun. It's a little bit on the slow side, maybe having a way of speeding up the robot but using more battery power or something would help. The big sprite animation when you start a game had me laughing for some reason, like something off Monty Python. The cleaning up gameplay is really satisfying, as is getting the robot to turn neatly. Nice job :)
