Cool. Good timing to receive feedback on it since I'm just now doing a sort of follow-up project.
My favorite VNs are ones that do actually implement standard RPG gameplay elements into the mix. I was lucky enough to have an English guide while playing Sakura Taisen 1 for PC last year, and it was an excellent balance between the both. I've always wanted to create a REAL visual novel someday, but I have to wait until the right story hits me in the face.
