Hey AGPX, I also posted about and recorded a video yesterday for this amazing game (https://vintageisthenewold.com/planet-balls-a-new-challenging-puzzle-game-for-the-c64-that-will-get-you-hooked/). It is nice to see something that are different once in a while!
I spent way too much time recording the video because I've got so hooked that I couldn't stop! This is certainly a professional-grade homebrew game for the C64. If we were in the 80s, this would be a best seller and you would be a rich man :)
