Absolutely heart- make that, dick -breaking even if it is understandable. Penny, Dalia and the other one* are the hottest part of this game. Frankly I wish there was more focus on them and less on the others. And their attitudes would REALLY drive a threesome, experienced tease Penny meets spicy 'tude girl Dalia, or some combination with unspoken connection and mature Nancy would be hot AF, and that's without the incest element. Moreover, couldn't Caribdis just start releasing a 'landlady' and her two tenants version of the game? Frankly, I'm not convinced this didn't start as/there isn't secretly a private version of Eternum that has Orion as Nancy's son. I'm not a huge incest fan, but it seems like that was the intention here. I mean, his "former nanny" has him come live with him and her two daughters? It's basically the exact same setup as OiaL (and every other long lost son Harem game ever made to boot).
Is it really that much work to just find and replace? That being said I respect Caribdis' vision and the number one rule of business. "Don't mess with the money."
*Just kidding, I know who Nancy is, and she's a peach
