A white human that can transform into a purple vortex that can go through walls? Good idea, but maybe you should communicate better that you can go through walls, it took me quite a while to figure out (I just assumed the same laws of physics apply to purple vortexes). It's a good thing that both forms have limitations, some time ago I made a quite similar platformer where one state was obviously superior. I'd put in some more polish into the movement, though.
