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.
If you have any question you feel I can help you with, please make a post in a help topic or a thread of your own rather than PMing me. You will get a faster response, and any mistake I make (and I do make plenty of those) can be corrected by our fellow forum members. Thank you.
If you want to PM for anything else, go ahead. Otherwise the only response you'll get is "post it here."
