For all people struggling getting to the end of the update, no matter which path you choose, you NEED to give the ring and nanobots.
If you don't, before the camping preparations, Richard will try to text you about the app, but since you don't have it, the dialogue doesn't happen, and you're soft locked.
I've also went to 94/99, idk how to get the 5 last.
All in all, I wasn't expecting much from the game, but I really liked the "flow" of the game. A good surprise for ppl who love NTR. It's refreshing to have proper Netorare made the good way, without Netorase. I hope you'll keep going in that direction and avoid NTRS as much as possible.
