This game is so cute!! I love the art style and the mechanics are so fun to play around with! There's a really fun sense of discovery to finding out you can jump -> swap -> psypull to get over a lot of things.
The last level seems a little arbitrarily difficult at points (after going up the wind it's really easy to mess up the psypull and fall all the way down and when you do get across I accidentally threw the princess off the edge of the screen because there's no wall there) but for the most part the game is incredibly well polished and fun. I could see this having a ton of potential as a Foddian-type game.
Great job!
