AAAH I love VNs in that setting / time period! So hyped!
I'm curious about the route system since you say it has two routes but a single ending. Can't really imagine how that would work but oh well, I'll see.
Lately I've been playing a lot of Red Embrace, even though I didn't test the newest route yet, but I must admit that while I loved the story, characters and art in that one, I'm not a huge fan of the choice/stat system you used. But it's nice to see you try new things with each new game!
