I really liked this! A very clever take on the "roles reversed" theme in so many ways! The level design was really clever and well-paced. I especially liked how the mechanics were introduced one at a time to give us time to get used to them. Very cool game! If I could make a suggestion, I'd say to try to make it so we can see both screens at once. Switching between both scenes got a little jarring a times and I'd often forget what puzzle does what or which character I left where.
I feel this is a really nice little puzzle game and I can see it develop into something really cool in the future if you were to continue this. Solid stuff!
