Bouncer

You have a class cast exception in Bouncer when you use other levels. You cannot cast Level2-4 to Level1. Also, may I suggest having a subclass of World to hold all your key methods(written in just Level 1), and then make your levels subclasses of that. That way, all your levels inherit all the key checking methods, rather than having to write them separately in each level.

This game is terrible. Maybe next time before you publish a game you should make sure it works. This is what is wrong with our country today. I honestly want to chop my sac off after playing this game. I hope you are proud of what you created.
