This is probably my favorite out of all the games I've played in the jam. The mechanic is simple yet complex at the same time. It feels like there's so much room for different designs and expansions on the mechanic. Like challenge mode to get the most quota, or maybe change it up earning the most money. Puzzle mode, where the player has a bunch of pieces and must create an infinite loop or whatever. Even player made challenges would work. I really like it a lot.
I only have 2 gripes with the game.
The first is the tutorial, but I'm guessing the tutorial is like this because of time constraints (mine was the same tbh). Aside from that, I think it would be nice to have an option for a more standard font for the text in the tutorial, as it was actually a little bit difficult for me to read the tutorial.
The second is the sound effect of the explosion when I accidentally made the same rotation adjacent was a little too loud. It kind of jump scared me. It seems to be because each spinner destroyed produces the explosion sound. When multiple of them go off, because the sound is the same, it just gets amplified. I tested it in sandbox and it seemed to be the case.
Overall, I really like this game.
