First, thanks for making the web version available! I wasn't able to play when I tried two days ago, since I use linux and didn't had any Windows PC at hand.
Now about the game, I like the idea of making a exploration game (or walking simulation). I wandered around for a while, and I can tell you I like your dream office. It reminds me a bit to my younger ages, when I struggled with Half-Life. I liked specially the set up (how the office is organized) and the big blurry windows, how the exterior could be anticipated from the inside. Also the little details (sfx of the walking, automatic door) are to be appreciated.
An issue I had (but maybe is from my end, since I don't have a very powerful machine) is that the control was too responsive. I don't know if it is only my case, but for me a reduced mouse sensibility would have been much better. The walking/jumping otherwise seems ok to me.
And as a constructive suggestion, adding a few interactable items to the game, like that automatic door, would help the game to feel more alive. Maybe even including some kind of (short) mistery / puzzle that needs to be solved. Although, as I just said, this is just a suggestion---I assume that doing all that 3d modelling was hard and took a lot of time. In any case, you constructed a cool scenario, so good job on that.
Good jam!
