It’s a mindbending puzzle. Admittedly, I had to give up when I was maybe one or two moves away from the solution. The melody came together pretty quickly for me, but the accompaniment was much harder to differentiate. The biggest bugs I found in the current build were the sliders on the settings screens starting at zero, and when moving tiles with the gamepad they seemed to always go left. I’d also be excited to see more puzzles and difficulty options here. Nice work!
