The character designs and their animations were great! The environments made of black and white shapes were pleasant to look at. There was some creative level design, I particularly liked the bits where you had to look at the area under the floor to know where to jump. The music was fine, but had a bit too much of a "pressured" feeling, and the loop was a little too short. I like how it reversed when switching dimensions though. The writing was funny, but I wish I could have clicked or pressed the button to make it go my pace. Nice job teaching the mechanics through level design.
