Really cute and abstract little game! I like your use of physics - it allows for both a puzzle-y element and some frantic energy. The randomly selected drops kind of reminds me of Tetris, and just like Tetris poor decisions can screw you over later on. You have to manage the board carefully. I liked the strategy involved with the different shapes, too: both the materials and the spheres vs. cubes. Also, cats!
I found myself losing really quickly for some reason. The physics of the game just seemed to respond really slowly? Once the platform started leaning one way, and the cats all flooded that direction, I simply couldn’t get it to tilt back in time even with triple the blocks stacked on the other side. The green and yellow shapes also disappear quick and don’t have a strong enough effect to do very much good (same with spheres which roll off very quick). I just felt like all my actions were weak, and the cats are so slippery I can’t deal with them fast enough. Maybe I’m just playing it wrong, though, I don’t know exactly how your physics system works!
Great job! This is a super original experience. (By the way, thanks for the disclaimer. I was concerned the cats were really exploding…)
