Nope, this is great! All appreciated. Dang, PC huh? I don't think an itch comment thread is the best for troubleshooting, but I'd be interested in knowing your OS/specs in the Discord.
One thing I might ask you, though, is to maybe move the spoilery bits "below the fold" of your comment (or move it to the Discord, even), just for anyone who hasn't yet played.
Regarding the story/structure/plot devices, I obviously can't say too much about this until the full game is out, but I don't think you have anything to worry about. Think of it like a Phoenix Wright game, if that helps: early chapters are shorter, simpler, and have mysteries that are easier to deduce, but grow in length and complexity over the course of the game.
