About as good as SMW rom hacks get. I was a little worried that it was going to be some kind of weird fetish hack given how Peach is depicted (and as an asexual I've just got no interest in such a thing) but it's actually really freaking wholesome. The aesthetic reminds me a lot of Super Mario Maker- but without the janky physics since this is built off SMW. A few standout moments include a sweets world where you'll find yourself jumping into a bottle of cola and swimming through it (castle of illusion anyone?) and a whole ass recreation of Buoy Base from SMG towards the end. 100% worth a play. Can also confirm it works perfectly on a super everdrive x5/snes model 3 setup for those who like to play on the original hardware.
