First try, got past the "go right to find your ending" sign, and kept running. I then missed a jump and ended up in "depression land". Attempted to climb out of depression and got stuck in a portion of ground when I jumped while underneath it.
So second try...
Managed to get all the way to a friend and then fell like super far and ended up in the ice part again, where I kept falling until I couldn't get back up and then was left alone in an ice cave with a dark quote from Dag Hammarskjold.
All in all it was great, nice concept but I think I've not got the dexterity to get any other ending than what I got.
