Played till the end. Well done! I think you captured your intended experience perfectly. Very chill vibes with the visuals and the audio. I was just a bit confused though about why the visual effects for the last level? Was it meant to be another mechanics that you didn't end up making in time?
I quite like the twist on the mechanics for a classic game and it does open up some new interest puzzle designs. Overall a very well done game indeed. Great job!
