I remember this one. I'm impressed by how this got better than before, especially in terms of aesthetics. Too bad that a hack deson't concernes aesthetics only~
The level design kept the same as the older version, more or less: as Jack stated in his review, a few levels are blatant edits of the original SMW. I know you said in PM that you made your levels from scratch, but even so, you should avoid making them similar to the original ones. Besides this, some sections are kinda flat too. I won't bother about this much though, since this is a first world, and some flatness is unavoidable for early easy levels, isn't it?
As I said earlier, the graphics NOW look good enough. Despite a few cutoff and silly FG + BG matching (like in the beach level), I'm considering the overall acceptable. A little bit of more working is appreciated though, as this isn't perfect. I'd also like to point out that some cave levels/sublevels still kept the SMW graphics. From my point of view, you should use a Kirby-styled aesthetic for all the levels/sublevels of your rom; or else, it will look silly and unprofessional.
As misc issues, I found the same ones Jack did, so I guess it's pointless to repeat them again. Be sure to fix them, since they are pretty annoying. Also, a thing I'd like you to do is to apply a patch that show the player's health, like this one
. Let's be honest: the dot on Kirby's head isn't the best way for warning the player that you have +1 HP. A subjective judgement here, you're free to do this or not.
Difficulty is easy
due to flatness mostly.
Due to a major glitch, which is music incompatibility with accurate emulators, I'd reject
the hack: keep working though, you're improving a lot. Do your best~
