Heh, this was neat! Needed a while to figure out how to progress on floor 2 and got stuck once because I switched with the wrong person, but otherwise this was a lot of fun. I’d consider adding a few checkpoints so you don’t have to replay everything from the beginning when you fail, maybe everytime you enter a new floor?
Apart from that, really good though, and I loved the little touches like the ballerina’s walk animation. Great job!
