I'm surprised I can still move after I played this.
This hack is awful, probably one of the worst I've ever played. The main offender here is the design, which is extremly flat and repetitive. Repetitivity is what hurted me most; each level is like "Hey I had this idea of making this particular section, let's spam it trough the whole level". This is, even, a big hack, so you can't imagine how boring it will become if you're aiming to 100% it. But that's not all. Another big complaint I have is about some levels' secret exits, which aren't intuitive at all. An example is "Wendy Koopa's Ship": a level with no horizontal scroll, where the keyhole can be reached by an exit located over the screen. You're unable to see it, and, unless you're the creator of the hack or go for a look in Lunar Magic, it has no way to be discovered fairly. This is just one of the many many flaws this hack has.
Aesthetic-wise, there are cutoff and some weird palettes here and there, but most of the levels look decent. Not much to say here.
As issues, I'd only point out some major slowdown occuring in some levels, which is very irritating.
Overall, if you're looking for the worst hacks ever made, I'd recommend you this. You will sure have lots of fun.
