Oh, I'm around! I just lurked for the first few hours, reading all of the comments and not replaying
The plan is to let the player experience both the romance and the NTR route in the early game, so indecisive players can pick whichever suits their fancy. After the SECOND expedition starts (not the one coming in the next update, but the one after that), the romance route will be inaccessible if you have too many NTR points. So even if you gather enough supplies, Nora will start refusing sex with you.
Yes, I am leaning towards one route - the NTR one. It'll get a little bit more scenes each update. Romance fans don't need to worry though, there'll be plenty of chicks who want to smash them, including a new one, which I already have the character models for- she'll show up a little later!

They'll have their own routes/dates/scenes.
About Evelyn and Parker - Yes, you're either her sub, or her dom. Or at least, will become one after a while. Telling Parker about her infidelity won't have any consequences for a while (if you took Evelyn's deal), but she will find out eventually that you were the one to tell him. Parker will also fundamentally change depending on what you told him.
About Julia - she's not the scientist's spouse, she's the wife of the shopkeeper, Rowan! And yes, she'll have romance events and "you watch as she fucks" events, lol.
I think I can handle it. The SUP was a lot bigger in terms of routes, so I'm pretty confident I can make everything coherent enough, it'll just take time. I plan to add 8-16 scenes per update, depending on how well the Patreon does, so in two or three updates I can properly update every single route. + The non Nora routes will be shorter and will have maybe 50% of the scenes Nora will have, too.
