I really liked the first third or so of this. The music and art are great and give some cool WarioWare-esque vibes which I'm really into. The problems come starting around world 3, where there's an unfortunate combination of really bad performance slowdown and difficulty spike. I died many times because the game was hitching too much too read my controller inputs. By the end I was just glad to have finished it. A more polished sequel could be great!
