Really nice work, beautiful art style, music and general SFX are simple in a wonderful way that highlight the theme. Great job and congrats on the Jam!
I didn't get it 100% finished but got to Level 8 or 9 and I had no issues particularly. The different form being on a different map was perhaps conveyed a little less clearly than it could be but I have no real suggestion on how to fix it, and once I worked it out it was quite intuitive.
