Absolutely crazy what you managed to make in 4 days!!! The game is smooth, immersive and good looking. Voice acting was funny, and I liked some of the references on the wall.
One thing I found not so good, was the puzzle... I don't know if it's a me issue, or the puzzle, but I really tried for around 10 minutes before quitting. I did understand that the call was supposed to happen at 3:14 and other stuff he mentioned, but I did not manage to do the puzzles...
Apart from that, great job overall and I wish you the best of luck!
