Interesting mechanics, the graphics are nice. I like the gray-scale rocks, and at least the first two plants stood out enough. They could either be brighter, or one of the first spells you get should highlight plants. Needs a lot more basic things, like some sort of introduction. Right away you give the player an increased jump hight, but there's far too many invisible walls on places that look like you should be able to land on them.
I'd be interested in seeing this in the future, but it's unfortunately far too unfinished right now. I don't know if you included any audio, but there was no sound for me. I gave good marks for innovation an theme interpretation though.
