Very nice puzzle platformer! I liked the art and vibe of it, and the light is great! The only major issue for me is that in some places only 2-3 out forms allow you to move further at all, so you just have to wait it out. And the flying one is just totally OP compared to the rest. A cool way to develop it further would be to allow for smaller forms to be also beneficial - e.g. to have places where jumping high is dangerous, or maybe size-wise difference. So it would be cool to have several alternative paths for each orb, to allow for different shapers to "shine".
But otherwise, it was fun! I didn't manage to finish with zero deaths, but I still made it :)
