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.
Wrote giant tilemap/clipping routines for the sprite. Added extra code to tile drawing routine so the sprite animates faster when its stun timer is about to run out. Removed unnecessary code. Added screenshots, tags and SA-1 support.
