This is quality.

It looks beautiful. The remixed themes are great.
Very well balanced difficulty-wise (unlike some of the other level hacks I've played)
So far I'm most of the way through World 1 with all the star coins/hidden exits.
I'm happy to see a lot of nods to Super Mario World. The game feels more integrated into the series than Nintendo's NSMBW! Cool surprises in the Yoshi House after hitting up the switch palaces
Only encountered one small bug so far that caused the game to stutter for a moment, but nothing major and everything's been gravy ever since
