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.
Very easy hack, but also quite flat and repetitive. A few of these levels feel the same, e.g. Super Run and Freebird. The castle gives you tons of free powerups and the Switch Palace is rather pointless in this hack since it takes you to the same place as the regular path with no perk to it. Furthermore, the Switch Palace level is nothing but entering a pipe at the very beginning and then the rest is the same. The first level is the only one that really felt like it was trying to do something, and these levels are too short for the ones that could be something to actually be anything.
