Played through the demo and I'm into it. I dig the Steven Universe inspired art and the "main character with anxiety" idea is pretty new. I'm sure that's going to go in an interesting direction.
Only nitpick is that I feel like the two-color tile puzzles at the end of the demo were easier to solve than the single-colored ones in the beginning. It was more obvious which tile was next when it was split between two colors. Just a thought.
Cool stuff so far!
