Thank you for streaming my VN!
Since I originally made the demo as part of a game jam, I had it start in the middle of the story when the string of murders begins. This is so demo readers could jump into the mystery instead of wallowing through the setup. The setup will be focused on the Slice-of-Life side of the characters and story, so the professor will get screen time then. That might mean I have to adjust the trial scene after adding the setup to highlight the importance of the professor like you said, but I think I might rewrite the trial scene in its entirety anyway and figure out how to either prioritize more emotional investment or make it shorter. But currently, I wish to write the rest of this route before I write the setup.
The vote between Cecil and Frederich will impact further murders, which means that point will branch out to two major paths. As of now I am focusing on writing only one of those paths so far. As for not being able to choose a third option, that will be unlocked once the two other paths are completed. Perhaps I should give the MC the option to vote for the doctor but give it a lock symbol to show the choice is possible but only under certain conditions. That might decrease the reader's frustration if they want to vote for the doctor.
Again, thank you for streaming it! Let me know what you think of the rest of the VN once you have the chance!
