It's mentioned in-game that this is a collection of old levels from the creator. But even then, it's still somewhat enjoyable, albeit kinda messy in its level design. The music choice is very good, it uses a number of popular songs used in romhacks, so it made the experience a little better cuz of it. Some levels in this romhack come from another romhack named "Despair Mario's Gambit", taking levels from that romhack and implementing it here, which makes things more familiar and much less creative. Then again it mentions that it's not meant to be ground-breaking or awe-inspiring, so maybe I'm expecting too much. Difficulty is very simple, I think the only level that'll give you some trouble is the WC level, and that's it.
I give it a 3.0/5. Despite giving it a low score, I think it's still an enjoyable experience, just nothing to really write home about.
