What a wonderful little game. I enjoyed my time with this very much.
I like the sounds and the visual effects and the place they create; it reminds me of some sort of educational short-film aesthetic from the early 70's, like Eames stuff.
I like the nudginess of player agency here. I never felt like I was in control of influencing the paths of the balls at all, but I could tell that I sometimes affected it. The esotericism of the feedback and scoring was enjoyable to hypothesize on for a good while.
