Nice effort! I usually find VNs boring, but I gave yours a go today because your game had high karma.
While it feels unfinished (missing sprites and so on), there are a lot of things to like about it. For one, I felt I had meaningful choices to make. I also liked the backgrounds, I think they suited your world nicely. And having different routes/endings is really cool for a mystery game, because, by definition, mystery games do not have much replayability.
All in all I enjoyed it. I look forward to the finished product! :)
