There is no code for jumping in the engine for this beta. This beta is FAR less about the engine and far MORE about the tool itself, and understanding how it can be used to manipulate the ASM underneath. I've tried to say it a lot...don't think about this as a way to make your first game. Think about this as a way to learn the basics of the tool so that come August, you're prepared to make your first game.
Love the enthusiasm though!
