Tip: If you give a Muncher tile custom graphics, it will still act like a coin when a silver P-switch is active, whether it looks like a coin or not. So make sure to use ExAnimation if there's a silver P-switch in the area.
You use comic sans, which looks very unprofessional.
Most of the "DO NOT USE/EDIT" could be removed, you can edit them, you just need to consider the extra info for the level.
Going to level 0/100 doesn't crash the game, it softlocks.
Big Boo Boss takes 3 hits.
No-Auto-Move levels don't move the player automatically on the overworld after beating them.
You could have documented level 24 (chocolate island 2) a little better.
You say the lemmy required hit count is editable, but so is every other boss's hit count.
IIRC most bosses kill all sprites when they die.
