As I am not familiar with the Fall Down game, all I can say is to create a basic world for you canvas and game states and behaviors by way of fields and methods, create actor classes for the different types of characters, guis, and interactive objects and give each their states and behaviors in the same way. Once you have done what you can with that, then if you have any specific problems, start a discussion.

Hey danpost First of all, this is the game http://www.albinoblacksheep.com/games/falldown We have already made a world with bars and all that. But we are having some trouble making the world (the speed in the game) go upwards, so the ball is falling down at the bars and through the whole at the bars. Can somebody please help us? Thanks /AHarbo and I
