This is what happens when you play too much Brutal Mario and SMW YEAH!!.
Design-wise, this hack is absolutely flat and boring. This is pretty much a sprite showoff hack, where in each level you face a different set of custom sprites. That's the only aim of the hack, so levels are pretty much a flat land with said sprites on it. Sometimes there is some trickery with the design, happening in levels like "Crazy Chapel", but it's not something this great; they're just... slightly not as linear as the other levels. Mentionable also the overly repetitiveness of the hack in general: just think that the castle level is a fusion of all the sprite sets in one level, so it's like you're playing a "summed up" version of the hack. Overall, not fun at all, probably one of the worst design I've seen.
Aesthetics are okay, but they're extremly clashy overall, no consistency at all. Atleast, there are no silly issues like weird palettes or cutoff.
As only issue worth of mention, music breaks on accurate emulators.
Overall, 1/5. Aesthetic-wise it's acceptable, but this hack isn't fun. At all.
