I like the concept and theme, as well as the pickaxe's hidden location!
However, I was softlocked after completing the first two tasks as there weren't enough trees to complete task 3 (Eastern sign from start). I think this may have been because it seems trees respawn after each task's completion, and since I had harvested the entire area, I did 2 tasks in a row without harvesting, leaving me 4/24 wood needed for task 3.
