So first of all, the city looks really good and I actually think the lack of BGM kind of adds to the game, making it feel a bit eerie, even if that's maybe not what you were going for :D
I loved that you could trip over stuff, at first I thought the camera was just kind of glitching out but that's actually a neat little feature.
Other than that, as was already said the town is very large, and some sort of navigation as to where to go would be helpful.
But for 48h this is still impressive regardless! (Also dealing with the mouse wasn't too bad, I just kept the game minimized and sorta did circles around the game window, it was kinda fun that way :D)
