The puzzles hit a nice difficulty balance, the visuals are super satisfying to watch, and the core loop is solid. The only thing holding it back is the complete lack of audio. Even simple SFX or a looping track would elevate it significantly.
I released a version 2.0 with an extensive background music track. I would encourage you to give it a try if you have a moment and maybe even leave a positive comment on the game page if you feel like it. And if you don't, hopefully no offense
