While the original Dr. Lunatic had cheats entered through the keyboard,
Supreme With Cheese has these as unlockable items instead.
Despite this, two cheats are programmed in Supreme With Cheese;
leartiste - Enables the level editor without needing to unlock it
scummypunk - Enables all cheats, but only if you buy the cheat menu.
Otherwise, the game crashes.
