Pretty good concept, just needs a few tweaks! The jump being the main tweak needed, there were times were I had to jump straight up to a platform, and because of the floatiness, the shadow was able to catch me before I could land a recharge my jump. Also, the scene transitions took a long time, and made having to restart a level a bit disheartening, I'd recommend reloading the scene when the player dies, rather than going back out to the level select. This is a good base, and I'd love to see how it turns out if you do go back and make tweaks!
