I can do! I hadn't planned for making one, but it's certainly something I can work on. But for now if you want to ask here I can help you out with whatever you're missing!
Yeah okay that one's kinda easy to miss without realizing what exactly you've missed because there's a specific single choice that sets it up and tbf it's not clear. So first you'll need a good score with Bobbie before the beer pong scene with the twins, and then pick "You think so?" when Jess asks you about her after the match. That'll lead to you setting up a date with Bobbie, and the scene follows from there (assuming you agree to stay the night at the end of the date, you do get a choice to not, but obviously that wouldn't unlock the scene)
Yeah, and I know that can be a little frustrating for people who want to see all the scenes, but it is intentional, as I want there to be some obfuscation as to what outcomes will come from the choices made. However, this is only really for first playthroughs to be fair, so I can work on a small walkthrough/scene guide for the future to clear up similar confusion. Thanks!
