I'm glad to see this game back. It has a fun premise! I'd love to see more. What if in later levels you had to get two humans to the end instead?
One glitch I encountered was that the human didn't go to the Huldra tree for some reason, instead opting to go up to the trees on the right, softlocking my game. Maybe it was because I pressed space during the transition where our player goes into the ground? I don't know.
