Very impressive game jam game. Starts easy and quickly becomes mind bending. I really liked the music that turned on and off with each world.
One thing I ended up doing which I didn't like was that I could use a very small platform on one of the screend and just go back and fourth to make the other player move a long distance, was pretty labourious but solved the puzzle. I'm sure there was a more elegant solution but when a dumb solution works...
