A really, really fun mod, I've found myself playing over and over with quite a lot variety.
My only gripe is sometimes I get stuck in areas which result in my death due to incredibly difficult platforming, such as the Post Crocomire Jump Room without powerbombs or speedboost or both, as well as coming in from the top side of the Crateria Super Room without enough room to break the speedboost blocks to go down and exit.
Otherwise, I've had a ton of enjoyment and can't see myself putting this down any time in the near future!
