Is it allowed to use classes, which I allready wrote? Because, in case, that I've got time, I would also join this comeptition, but I would use some classes, which I already wrote. This would include my Scrollworld-, Slidebar-, Mouse-, Time-, Button-, Point-, Vector-, SoundPlayer-, MusicPlayer- and MusicBib- class and maybe also my PlayerInfo-, TickBox-, Darkness-, Glower-, ValuePainter-, Image-, ImageManager-, Picture-, LetterTranslator-, Highscore-, Sparkle- and Ash- class. These classes are no classes, which I will use to program the game concept. I would need them to make the game complete, that it looks better, sounds better and that the game runs smoother.

Yes, you can use support classes (especially if you wrote them yourself). If you use a support class made by another user, you'd have to credit the user. As long as your scenario is more than just support classes, it's fine.

I am allowed to join more then one level at a time right? I'm only allowed to win one though I know that. Lastly can I make a remake of an old game I made, starfight, with new code and images for the expert contest.

Yes, you are allowed to make more than one game (as long as they are each in different difficulties). You can only win once, yes. As for your game, I see that it is already a remake of space invaders, but I would rather you remake another game. You already know how to do space invaders (even if you're starting completely over with the project and/or adding new features), so that would be kind of an unfair advantage.

PONG IS TAKEN NOW MUAHAHAHAHA (I call pong :D)

I am uploading Mr Cubemans Maze now. I will update it again within 2 weeks (it isn't done and I wont have wifi for like 10 days). I just need to add some scrolling (and more Maze/puzzle like) levels.
