I had a lot of fun with this game. The topic-linking mechanic did a great job of having the gameplay feel like being a tv-show detective, rather than someone who happens to solve a case by solving text-adventure puzzles. It gave the game a unique feel that I highly enjoyed, and the characters and descriptions definitely contributed to that feel. All in all, it felt very well-polished.
In the end, it seemed like this game had cool mechanics but wasn't necessarily maximally suited for a parser game. (Spoiler - click to show)In the present, really all you did was decide who to talk to, which topic to bring up, or what to link. The flashbacks were mostly fake interactivity and while it was cool to see the same places from different perspectives, it got old to repeat the unchanged parts of a flashback. I would've enjoyed a few more layers with less-obvious linkages. Also, I was disappointed that the color-based perspective didn't really end up being relevant to anything.
That said, I enjoyed this game and its link mechanic a lot, and look forward to future games by this author.
