To preface - I'm not very good at rhythm games, but the art style was enchanting and I had fun playing with my friends and watching the dance animations.
Having to control both the arrows keys and WASD* does make it a unique game in the genre, but it got pretty overwhelming pretty quickly - still, you all did a great job making a bug-free and funky fresh game.
*(In all fairness, a controller was highly recommended, but we didn't have any!)
