You obviously have a talent for writing, and I encourage you to try to make a living out of it. Im curious, did you ever take writing classes?
Regarding the game, it could use multiple save files and some fast forward option (autoscroll is not enough even at 0 delay) like other visual novels, because even if its one of the best written novels in this site, its also so uncomfortable to replay that it makes me not want to.
I also found a lot of bugs that trap you into loops repeating the same dialogue over and over. Some of the loops I found were car->japanese->doctor->car->etc and the game sending me back to interview the jap guy a second time after solving the case in a single day. It probably has something to do with a messy code and clumsy implementation of flags.
Last but not least, are there any other visual novels that you would recommend besides hotel dusk?
GG.
