Definitely has a clean style and an interesting set of mechanics. I'd say the game is maybe a little too confusing to get through without a more thorough explanation of the mechanics.
The idea itself is one I think most people thought of but you actually managed to create a charming, fun game from it. The idea is an obvious one yet the execution is stellar. Definitely an interesting puzzle platformer! Great work!
Cute pixel art and the idea behind switching every so often is a really good one. I do quite like that as an interpretation of Role Reversal. The platforming is a little too unforgiving though.
