When I first heard about this romhack, I didn't initially play it. I would join servers with friends or publicly with this on, but never really had an opinion on it. But after playing it in full, I think it's a great introduction to romhacks, alongside Star Road. Each star has their own unique solution, with varying, interesting puzzles that makes each course feel fresh and unique.
The difficulty is pretty easy, with a few difficult stars to spice things up, and the music choice is nice. Each track fits for each courses' respective themes, but I wish the Bowser + Slide level had some custom music of its own. I do wish there was more courses or even random NPC's around just so it stands out in some way, since the romhack does feel kind of generic in terms of atmosphere, with the same cookie cutter grassy plains, sunny beach, snowy terrain and hellish level.
Overall though, I believe that what this romhack does does it exceptionally well. I highly recommend this to anyone looking to explore what good romhacks have to offer.
