Awesome puzzles, and it feels great to play, the rotation, the sliiiddey boi when I hold down a direction...great stuff. The flow of levels/introducing new concepts smoothly could be improved, I had a fun time but got hardstuck on level 15 :'(
Some levels I felt like you can only try 2-3 things, so I just explore the decision tree and solve it and feel like I didn't really learn what that level was trying to teach. That was still fun a lot of the time, e.g. level 10 was awesome but in the moment I didn't really "get" it, I just tried stuff. On another note, level 12 was my favorite, it made me feel really smart, but then level 13 felt like it was a step back, like pushing the gear should be introduced before pushing it in a more complex way.
Anyway overall had a lot of fun trying it out :) I wasn't in the jam, just saw it on Juniper's jam video and thought it looked really cool (I play other sokoban/puzzle-y games a decent bit).
