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.
Had to optimize some leftover code from way back when this was a patch. Please be more careful when updating these old resources.
Works decently, but it's weird how the player just suddenly 'brakes' if their current speed is higher than the desired speed when ducking.
