I thought this was a fun hack! I liked how you made it feel like Captain Toad, so it was fun! One problem, though:
The first three levels of World 3 are tougher than anything else in the entire hack due to the randomness of the generators. I'd recommend you try to find some other way to make obstacles in those levels, personally- it's just so random that sometimes, you're guaranteed a death because of something you can't see coming, and there's no way to avoid it due to the lack of jumping. Remember, those were designed with Mario's abilities in mind! The Eerie Generator in World 4 is much more bearable despite spawning more often due to the level only scrolling in one direction and not having as many note blocks, though those still cause trouble from time to time.
