Hmm, it seems the key to unlock the Director's room is not functioning right for me, I tried aiming all over the door and then using the key in the inventory menu but it says it doesn't fit. I also restarted the game and tried again. I watched someone doing a play through video and an option to use the key appears for them when looking at the door and in inventory but that option does not appear for me........

button config is great !

I ran out of house, into the field and to the end and saw the credits but i still did not receive the end? achievement
