Oh wow. This is incredible. The audio and the visuals are excellent. I love the mood that you have set. I wouldn't be surprised if this got the first place. It would be well deserved. Amazing job.
It took me a bit to set the mouse sensitivity (you have a type there btw) and doing so while getting chased by chairs was a scary experience. I suffered some rapid camera movements after choosing an upgrade which wasn't a big issue until later part of the game where I got stuck in a huge group of benches and almost got mauled to death.
Overall, absolutely awesome game. I would dream about chair apocalypse again.
