Very impressive, extremely well done for a jam game! I will say, I got stuck on one of the rock puzzles because they kept glitching out. Some of it was seemingly intentional (it felt like invisible walls were blocking some of the rocks from going into certain spots), other times I would just run close to a boulder and accidentally push it in a direction it wasn't meant to go (as in I wasn't supposed to be able to push it down, but running down whilst next to it would drag it down with me, etc.)
Overall a really cool game, I really tried to figure out a way to do the rock puzzle that didn't end up soft-locking me due to invisible walls, so I'm sad I didn't get to see the ending.
