I wrote a ghetto imod for myself (Sorry, won't post it.. I made it too custom for me) - It wasn't that hard. Beyond changing any of the normal things, like stepdaughter to daughter and what not, you also have to read the dialogues to change the conversations somewhat. Otherwise, it sounds too weird.
For example, there's a spot where one of Tegan's friends mentions that she didn't know Tegan had a father and Tegan respond's ""In fact, he's just my STEP-father, but that's a long story, maybe I'll tell you one day..." - That would sound weird just changing it to father, so i changed it on my game to "Well, he was never around to be my father, but that's a long story, maybe I'll tell you one day.."
Right now though, the game only really has two paths... good route and rude route. Not much of anything you do (other then that main choice at the beginning) will make much difference. Except, I think, getting them all angry at you. I really think this game should just be a straight linear VN. It sure isn't built to be a sandbox.
The point system is also very confusing. Why do you lose points for staring at someone's ass when they don't see you do it? And to make it more confusing, you gain points for staring at Hannah's ass - WTF?
Progression is also way too fast. By the end of this chapter, I had every LI in the game wet for the MC after only - what? - 3 days?
Anyhow, I like the concept and I really hope the dev fleshes out the MC's backstory from prison. It's refreshing playing a game where the MC is not some dork with a horse cock.
