Not bad at all! For how linear this one can be, it was fun to play. The design keeps in a traditional way, while being varied enough to be fun. Some repetitive sections are frequent though, as well as lands where there is nothing going on. The latter levels were a little better than the former ones; not sure about the difficulty, I'll set it to easy, since it's indeed easy to complete, especially if you manage to keep a Flower Powerup. Chances are big, since the hack is full of powerups anyways.
Aesthetics are nice overall. There is some cutoff here and there (mostly ground + pipes), but for the rest, it's well assembled. Not much more to say.
- Music breaks on accurate emulators.
- Major slowdown occuring pretty frequently.
Overall, not a top quality hack, but it's still fun to play.
