Hello! I have already tried your game and I have enjoyed it a lot. I was reading in the comments that there was a fatal error in a certain part. It also appeared to me, although only once. This happens when you open the door on the floor and interact with the phone before it starts ringing. Try doing that, if it also gives you the fatal error it's because we found it :) otherwise, it can only be occasional, that is, it doesn't always happen.
