I like the switching the different ways you move. Adding move objects that do things would improve the game further. Like moving platforms, Coins you collect to progress further, one way walls, fire that shoots, portal, trampoline, and things that shoot you a far distance for some ideas. You could also only use like one switch mode for some levels. There's no reason that every level needs to use all of them. Ideas for more abilities: Can jump has much as you want, warp one tile to the right or left, and move double speed.
