At any time during your game, type:

holyheck!

exactly like that, with the exclaimation mark. Now a dialog box will pop up. This is leroy, our friend who will help you out when you need it. Here's what he can do for you:

score = Want some free points? go ahead.

re-entry = You got kicked out of that contest? No problem. He'll pay off the judges and let you back in.

tron mode = The name speaks for itself.

extra-life = Running low on runs in thrash mode? Once again no problem.

summon semjase = How's about inviting that UFO over to have some fun? alright!

beach nav mode = Screws up the beach scene navigation, making in navigatable in a way similiar to doom. You cannot actually do anything
in this mode.

cheat keys numpad = Enable the use of the in-game cheat keys on the number pad. More about them later.

Try clicking on leroy himself for some better info on the music on the cd.
