This is a cool premise! I definitely could have done with more instruction, though--when I entered the different houses I didn't realize there was going to be a timer, and when I found the documents I didn't know I'd be able to access them outside of the house and I thought I had to read them all on the spot. I also didn't know that when I used the door, I was going to have to pick the murderer right then and wouldn't be able to go back and look at the documents again.
