This is nice. With a bit more diversity in the situations it would be really fun and replayable. The timing was remarkably precise. I almost always got to the point where I had enough information to make a guess in the last 30 seconds or so.
I found the writing kind of rough. The hard boiled detective style is totally appropriate but it felt like it needed some polish. In particular the first couple of comments on the mansion from the detective were cute but after that it just seemed monotonous and whiny.
The escape key doesn't restart the game for me in the last screen, I had to quit and relaunch to get a new scenario.
