Ch 7 tips so far would be... just make sure your inventory isn't full.
Edit: Finished the chapter. Definitely back on the same grind I had before the cheats by having to view each protag's route one by one. I'll wait for the guide to unlock the scenes I probably missed out on. Not my favorite chapter tbh. Erland's bottom scene was hot though. I liked the insights of each character but... nothing much really happened? I enjoyed previous chapters a lot more. Both story and scenes wise. Still, kudos for the dev team because I know it's hard to make this stuff. I'm excited for the next two chapters. We're really nearing the end now. I'm going for the progressive route so I hope we can see rest of the world being habitable and women going back to normal like the men, just like how our current world is and all our current story would somewhat be treated as a myth. To me, that'll be the happy ending.
Edit 2: Did you guys check the upcoming game Hunky City? It's got a non-traditional gameplay style like this game. Actually even far more open and less restrictive.
