It was surprising to find out that the player moves automatically, I thought my keyboard was broken at first! Maybe this kind of puzzle would make more sense if the player was stuck in a minecart?
The loop puzzles are a unique idea, shame that you didn't get to finish before the jam ended. I found that the camera was bugged (the photos didn't show up in the gallery) and the rocks on puzzle 2 kept disappearing when I tried to throw them.
