I must say the RNG of this game can sometimes suck!!!
And does anything happen with Nora and the cell phone if you text her in the morning or evening?
She always seems to be busy for the biology questions or when you ask her what is happening options for me.
I will just answer the Nora part of this. She needs a pretty high slut score to start the events from the cell phone. She can come over and "study" with you, with you and your mom, you could go over to "help her move furniture" on the weekends, and she does some interesting things on the way home with a cop while talking to you. But you have to get her numbers up to do anything.
I don't cheat and change any scores or edit the files to reduce resistance faster but I do make liberal use of quick save and load during the game to get the events I need at any particular time. And I don't often bother with anything other than blue serum. After you get the door code, you can crank out lots of it and with the newer hub scenes you can find events to lower their resistance quickly.
I like that the game is completely open, not that a RenPy game can't be decompiled, but you don't have to. I spent a bunch of time cleaning up the English up to v0.81 so I saw how the game works under the hood. Vren has evolved his style during the game and currently it is quite easy to add events and to track the new material. I really need to get the current version and send in fixes, though the last one I worked on was quite good. The hardest transition was when he broke the single script file into intro, major, minor, hub and script files. That took some time and cutting and pasting to make my edited single file look like his multiple files so I could see what fixes of mine he had rolled into that version.
Now I drop the new files into WinMerge to track the changes. I fix language in small added sections right in WinMerge and go into Notepad+ for the new sections. I don't change game logic, though I did do a couple bug fixes along the way.
I do miss seeing the MC. And keeping the girls to the outside when only one is displayed is kind of odd to me but it is his style. I would center them myself, but then you run into the problem of dialog choices being on top of them occasionally.
Public slut: how far from reality is making your sister walk around the block nude with whore written on her? Or turning a college lab into a whorehouse after hours? You would think the authorities might eventually get interested in him. Yes, there is the government taking over the research aspect, but that seems to go away based on LR2. Vren seemed to slot Alexia into that role from the beginning.
Cumslut: How hard does he need to work to make Stephanie a cumslut? Seems she likes it a lot from the beginning.
Anal Slut: anal has been in the game for some time, but you needed to get their slut score pretty high before the events would trigger.
Pregnant: with all the fucking going on, there really should be a concern, or at least some mention. Ker fixes it in Harem with a few lines of dialog and then the MC can fuck all he wants without concern. Maybe there needs to be something written into the endings.
And about all the fucking, you would think the MC would have to invent a serum for himself to keep up the pace.
You can cum from morning to night ever day towards the end of the game. He could at least get dehydrated!
