When I first saw this I though it was just some cutesy kids game, it's actually a cleverly designed puzzle platformer.
The interesting thing is they never explicitly explain how to do anything, you learn by observation and experimentation.
You never get any more powerful, what increases is your knowledge of how things work.
It has moments of frustration followed by moments of clarity when everything suddenly become obvious.
It's those epiphanies which really make the experience satisfying, and make you feel smart.
My only criticism is I would have liked a tiny amount of exposition just to say who I was and what I was doing.
