Hey, thanks for the feedback!
Oh yeah I feel like we've should have explained jumping better - it just works like swimming, you need to go to a wall / an edge and have the jump fruit effect active, then you see a prompt to interact.
It was obvious to me that it worked that way because I developed it, but i only now realize that a lot of people probably missed this. I'll try to put a pointer in the game description later as well.
Also, there should be around 7-9 campfires = wood piles around the map
