very kind for notifying of the errors, I fix the puzzle, and I put a ladder under the well to return to the main area, the idea was that this last area was to spend all the accumulated resources, I didn't think about that, sorry
No apology needed, the game was free. Survival horror also typically requires the player to conserve ammunition, but I made sure to kill everything. I think a good solution would be that if you run out of ammo before or in the cave, the villagers behind locked doors will have more to give you.
