Very nice game overall, it reminded me of The Silver Case somehow, which is good, also nice Philip K Dick vibes from the plot. The visual style and music were good too. Unfortunately I still have to finish it, maybe I'll update my comment when I manage to.
I only have 2 minor suggestions: maybe give the option to use a different movement system similar to The Silver Case in which you don't use the mouse and when you press left/right the character just turns 90 degrees: it would streamline exploration in my opinion.
The other thing is just a nitpick I guess but, have you considered using a non-serif font for the dialogue? I think it would fit more with the atmosphere of the game.
Good work!
