Clever premise. Pastel coloring is an unusual choice for a noir story, but it's distinctive. I loved the Raymond Chandleresque voiceovers. The high-res faces on the low-poly bodies are super creepy.
The music could be louder considering there aren't many (any?) sound effects.
I think I ran into a bug with Rachel... I delivered her letters, but I wasn't able to speak to her again afterwards (no prompt would appear to interact).
