Very nice, unique art and a beautiful inspiration :) I hope you continue with it to show your true vision of it.
About the gameplay. I'm not sure how jump works exactly. Sometimes I would jump very low, not even half the distance need to get to next platform. So I was sometimes loosing because of the low jump and when I went the wrong way and there was no platforms on my side. But the backflip jump is cool, reminded me of Icy Tower and felt nice when it happened :)
Keep it up!
