Thank you so much for playing the game, and it was especially kind of you to give it a try, even without being a Lupin fan! Outside of Lupin himself, Jigen is my favorite, and I agree with your taste. He’s very cool, but he has a heart that you just ache to keep safe. And he’s such a smartass; he has some of the all-time funniest lines in the show.
If you ever decide that you’d like to try a little bit of the series, I have two recommendations over here for first timers: https://alexis-royce.tumblr.com/post/688425799721910272/would-you-recommend-lupin-the-iiiwhat-advice
I wanted very much to make a game where the stats communicated the same way the words did. I think that visual novels that show the outcome of choices while playing are a genre that need to be expanded upon. It seems a little like sacrilege but I thought that the mindset that seeing those stats could put the player in was worth expecting. And the friction between choosing the stat options you need to advance, versus what a player might actually want to say interested me! Chapter three was an especially good place for that; I wouldn’t go so far as to call that chapter an “anti-dating sim,” but I did want to make the player do pretty much the opposite thing that any romance game would expect, mechanically.
