I remembered this weird social experiment game and can't find it tell me if this sound familiar

so the game is in first person but all the objects are 2d sprites and basically in the game you have leave a village to go into a cave where when you enter you see a person and you have the choice of killing them or letting the leave and after that you just continue on exploring the cave once your done you run back to the entrance of the cave where another person confronts you and then games reveals the person you saw at the start was the most recent person who had played the game and it says that the next person who plays the game will decide your fate and the game will email you later on to tell what happened to your character

does this ring a bell for anyone?
