This hack is a challengy one. It doesn't do many thingies, but it's not awfully bad.
The design is most of the times linear: the author added the wall-jump gimmick as main thing... which is used frequently in his levels. And that's about it; that's the only gimmick the hack uses, if you don't consider the Switch Palace levels. Not much more to say.
The aesthetics kept vanilla in GFX, though I spotted some custom ones rarely. They are okay, though sometimes the levels felt a bit empty, mainly for lack of decorations.
As only major issue, music breaks on accurate emulators.
Overall, not a very good hack, but it's not bad either. For a small challengy hack, this one could go.
