Useful Cheats

Revised Moonjump (Hold L)

The moonjump cheat that most people know has the side effect of stopping the player's horizontal movement if they crash into a wall or if they start a moonjump from stand still.

This version of the cheat fixes those issues, and allows the player to always be able to keep moving horizontally while levitating. This version forces the player to be in the "jumping" state (so that the player can always move while in the air), plus it forces the game to execute the functions that calculate jumping movement while doing the moonjump (this prevents an issue where, if you were sliding and then started a moonjump, you wouldn't be able to move horizontally).
