Nice game! Congrats. I like the visual style, I like the block faces changing around and the little yips that they make.
For the first few levels I enjoyed the herding cats aspect of it, but once there were a bunch of blocks jumping around I just stuck them on the right side of the scale to keep them from leaving. I also didn't realize until a few rounds in that you only need to balance the new item, and you don't need to use all the items on screen. That made the game much much easier.
Overall I had fun with it! A nice take on the theme, super cute, and I played until a few forever cubes in, so I was engaged enough to finish the demo! Well done!
