On your way back to the exit, you'll run into a wolf, which will trigger another mini-game. Start by wiggling the analog stick left and right (or pressing directional keys), then press the indicated button in the right moment (screenshot).
Next, keep tapping the action button. Get ready to press the indicated button again (screenshot). Finally, tap the indicated button to finish the wolf off (reward: 25 XP).
When you leave the cave, I suggest using the zip-line on the right; you can slide down it in order to reach the main area of the village much quicker.
The final part of the task is much less complicated. Run through the whole village to reach the first camp (Village Plateau) where the seriously wounded Roth is waiting for you (reward: 500 XP).
