Very charming little game! I like the tutorial style as well, but it had me wondering if the green orbs held anything LOL. The controls were a little tricky. The mouse look is pretty instantaneous, and I think it would be useful to be able to look up for the spots where you're "scaling" :). I know that camera following is tricky though, so I consider this minor in a game jam.
I noticed from trying it out that you had some gamepad support, but it didn't seem to have all of the buttons. Mine is the typical Logitech USB Playstation-style. I was able to jump and move, but the right stick did not look around and there didn't seem to be a replacement for 'F'. Didn't affect my enjoyment, I just used the keyboard as instructed, just FYI.
Great music! Set the mood right from the start.
