In the tutorial map, it wants you to set up camp, and to do that, you have to click a slab or table,. Towards the top fo the screen,the top of  a tree is visible.If you travel around the rockmass right of the slab, you can get near the tree. If you jump left (or top) of the tree, you die. If you jump to the right (or bottom) of the tree, you're stuck.

If the pictures work, in picture 1 I arrived at the location in the tutorial-area, in picture 2 I travellaed around the rock and am above the tree. And finally, in picture 3 I jumped next to the tree, and am stuck forever and ever with no way out.
