One of the better games I have played throughout the jam despite its simplicity. I could easily see this idea expanded upon into a fully fledged game. There are a lot of possibilities. Perhaps a slight oversight on level 2 where if both characters are in the area with the button, you essentially soft-lock the game because neither character can jump out and progress to the goal. I couldn't figure out a way of getting out. Also, maybe try experimenting with a physical camera or various camera settings so the camera doesn't clip out of the map and obstruct the views of the characters. Other than that, great job!
