I would recommend this to players who want to try harder romhacks but aren't quite ready for kaizo challenges. Gets pretty difficult without feeling cheap (most of the time). Early courses like the Whomp block fort do a great job teaching the kind of movement that will be necessary later on. The difficulty curve is mostly fine, but some of the later courses (not counting the extra challenge course 15) do get a little carried away with crazy wall jumps, timed block platforming, and tons of instant death pits.
The Bowser stage especially got somewhat exhausting, being a pretty long gauntlet where just about every obstacle is an instant death hazard, topped off with a pretty underwhelming Bowser fight that's actually easier than the vanilla game's final Bowser.
Overall though, a fun, difficult romhack that never gets too aggravating, but is brought down a little bit by a few of its later courses. I was able to get 121 stars before it became a bit too much for me.
