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.
The design is pretty good for a world 1. Even if sometimes it could be a little bit flat, it's still varied enough to be fun to go through. The author also uses some custom gimmicks, pretty much the ON/OFF switch gimmick in the castle level. The rest keeps as a traditional SMW hack.
Aesthetics are good. A mainly vanilla hack, with just a few edits of some global tiles, like the question blocks and the cement blocks. The palettes are good, as well as the overall environment of the hack. Not much more to say.
The only issue worth of mention is that this hack breaks on accurate emulators.
