Played through the game in one sitting and got all the stars. Really well done! The mechanics are easy to understand and unique, and I'm impressed at how much puzzle variety you've extracted from the simple rules of the game. It has a smooth progression of difficulty, and a satisfying ending :). I only encountered one bug: sometimes the music tracks from previous areas started replaying in new areas; this caused a lot of overlapping music to be playing simultaneously at some points. Regardless, the audio was great and matched the aesthetic perfectly. Loved it!
