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 GFX in the demo are bright and happy, and the level design is deep. Difficulty ranges from easy to medium, so you won't have a hard time beating the levels. It was made before the advent of AddMusic, however, so it uses the original SMW soundtrack.
Graphics are simple, but colorful. Fit very well with the Yoshi and Kirby rips here and there. Level design is enjoyable, and while this didn't have any custom music due to its age, the vanilla soundtrack worked just fine.
Do check this out whenever you have nothing else to do.
I wish cwiarl would have continued it.
