I had a lot of fun playing your game. First of all: The Graphics are amazing. How did you do that? Everything is smooth and fits to every other parts of your world. I had to play alone with two windows opened but after some levels I had to quit since they I wasn´t able to play them alone. The levels I played were great. The sounds and the music fit very well. Perhaps I´ll try play your game again with a friend.
I´ve submitted a local multiplayer game: https://itch.io/jam/brackeys-4/rate/722755. I would be happy to get your feedback on it. :-D
I´ll also post a comment on your topic.
