I think the only thing missing is allowing me to take a 3-minute bathroom break or walking out the front door for comedy game-overs. :)
I was glad to see just how many examines there were to find. Once I had a couple plays, I decided to take my time and read as many of them as I can. You've really filled out this fictional office history in a (frightfully) believable way.
For a game where clicking is the main input, It definitely didn't feel as clicky as I think it could have. Some text was hard to be legible for someone as dyslexic and with as big glasses as I have. A couple of times I was really juggling around my WASD position to look down right at a desk.
I think three minutes is a very nicely tuned timeframe. Almost as cruel as 72 hours to make a game. Nice work on getting me (and apparently others) to replay so many times on the strength of your writing xx
