Figuring out the puzzle is pretty satisfying. Was not sure how scale comes into play. Maybe the background change would have been a good indicator you are going up the mountain. Speed controls don’t save between levels though.

I was going to make the background pan up with parallax but didn't have it working nicely in time unfortunately. I considered the game fitting the theme because you are "building" the levels for the robot "to scale". And the speed control thing others have mentioned, I need to add that in a post-jam update. Thank you for playing!
