well just as examples- you could've put an ending around the skull so if the player gets near they get an ending thats like "oh no you died" or just like put an ending where the exit back to the previous room where you came from would be so you would get a game over instead of getting back to the path and it could say like "oh no they skull summoned the bears(?) and you got mauled" (sorry i dont remember if the game says bears or wolves >.<;;) "the bears(?) ambushed you and mauled you" ...yeah its sounding pretty grim lol but yeah that's something i was worried about when i went down that path
sorry for such a long reply ^o^;;
