Amnesia the dark descent part 1

I had made it out of the study alive. I had to find out where the key went I looked down the stairs that led to the locked door. I walked down the stairs and used the key on the door and it worked! I went inside it was a dark room. my eyes could easily fool me in here. I had to find the four ingriedients for the acid. I went into a room and saw a jar on the ground, IT WAS ONE OF THE POTIONS! I picked it up then suddenly support beams and big rocks blocked the door. I looked up and a barrel fell on me. I woke up an hour later I could see I could easily move the debire from the door. I moved the debire and left the room.
