Well, the space you've just exited from is the (rather sparse if I'm honest) front display of the office. It's where we posted every update we made to our work, as well as pointers to where you could access it. Think of it like a noticeboard, just... one that's on the ground and leant against the wall, with yellowing pages and dusty thumbtacks.
Now, you should be in the front entryway. If this is not where you expected or want to be, the exit door's right over there.
Please excuse the makeshift appearance and unconventional format, this was a rather spur-of-the-moment idea, and I had to give you at least something to look at while I work on setting up other things. It turns out that it's not an easy thing to translate an entire physical space into something tangible (?) on your end, and this was the best I could do. But not to worry—there will be visual descriptors everywhere so you won't be wandering around blind (these will be denoted by an * (how fitting!)), and there's a sign on every door, so you can't get lost!
You shouldn't, anyway... The office is only small but I may have forgotten to lock a door somewhere, or close a window...
