I feel like there is a lot of depth to this game I have not discovered. Initially, I clicked around on the computer and chuckled at the stuff on there - then I moved the cup and bin - nice! I almost gave up at that point thinking it was unfinished based on comments here.
I accidentally pressed R which made the game start over. This time I did similar things but at some point arrows came up to allow me to leave the cubicle. I went to the chairs, I clicked them a few times and read the quote. I also noticed the reflection on the left was a location icon. But I couldn't work out what to do and didn't have any motivation to do so because it wasn't obvious to me that it was a puzzle of any kind. But based on comments here the chairs are a puzzle that require a particular action.
I'm reluctant to open the game again to try the chair puzzle because it was kind of lagging and time-consuming waiting for arrows to show up and possibly not showing up at all. I think it would be beneficial to have a regular first-person controller to allow the player to walk around freely.
In any case I feel like there is a lot here that I have missed which I feel bad about because it looks like a lot of thought and time has gone into the game.
