This game holds a lot of potential. The writing and dialogue is spot on, the visuals and main menu music, although simple, really had this "police/detective game" feel to it (reminded me of this game called "Police Stories"), and the AI generated voiceovers are stellar (I really hate that one guy, because I was suppose to and his voiceover was perfect, so yea job well done).
As a game designer myself, I have to comment on the core gameplay itself. It's amazing how this gameplay grounds itself in simple straight up detective work. You got your diary, you got all your notes and there is no handholding, you need to figure things out, talk to people and glean information from them, connect all the dots by checking your diary. And if you get stuck you can "stare at the bottom of that whisky bottle" like a true noir detective. And all this comes together very well.
A simple yet well executed game design. Which is great and also sad because I'm terrible at games like this and I got a headache playing this one :P
I would love to see this developed further.
