What a fantastic puzzle mechanic and a well polished game overall. It took me a bit of time to understand how it worked. I love the aesthetics of the game, the difficulty ramp between levels, the music / atmostphere and how it fits the theme. I love that you added a Ctrl-Z option because so many times I regretted a move I had just made. I got stuck on level 6 or 7 I think, I just couldn't quite figure out how to get both balls in... I do plan on returning to this game and trying to finish it!
