I would tell the tips for maze in forest. Because some people complain about this puzzle. “It going so hard to solve with clueless paper.” they said. Ok I accept that;
First, after get the paper (or cutscene that somebody killed) just move to another map.
Second, you can see the rock in middle of map, after that just follow my instruction path:

up - right - down - left - up

and solved!

Q&A:
Q: So what’s the paper function for puzzle clue?
A: It tell the turn of path, but I missed to tell the rock in middle map as the start point.
Q: I never see the puzzle in that paper. What kind?
A: I think it was famous puzzle, but I wrong.
