It might be possible. The thing is the possibilities are huge.
And what about Eric? He's a delicate guy to handle. For now, my idea is to have him appear later.
His story will be different. The NTR (if there is one) will be totally avoidable. Those who like sharing girls will like it, and those who want to throw him under the bus will too. I will work hard on that, mostly because I don't want to be hated by the community.
For now, though, I'd like to develop other aspects of the game, especially the relationship between Lisa and Max, which wasn't explored enough in the original game. And yes, I'm talking about having sex with her—not anal sex
It's also important to me that Max not be a little pervert but rather a guy who loves his family but is also tempted by his needs, which are too hard for him to handle. The same goes for Lisa. For example, her relationship with Billie (the new girl) makes her jealous, but it's deeper than that. Even Lisa doesn't understand why she's jealous.
I want my characters to be more realistic and organic. Lisa is a teenager trying to understand sexuality. Alice is the rebel who wants to make money without working too hard. Ann is a mother who is stuck between her job and her family. She doesn't have time to find a boyfriend. Kira tries to reconnect with her sister and seems to hide something deeper.
I want this game to be more than a copy of a harem game where you click until you have enough money to finally sleep with your aunt because she's...weird.
That's why I'm confident that I can give you a game that will be different from others that have tried. It won't be abandoned in six months.
