Is it possible for you to make an option to basically not have to choose between the girls? You've already basically done a mini version of it with the choice to do multiple choices in the same day so I don't think it'd be that hard as all you'd have to do it remove the branch locks(though I don't know as I'm not a modder). It'd probably be the single best thing any modder could do to improve the gameplay experience because the whole game essentially leads you on and then forces you to cockblock yourself. It feels to me like the dev just trying to extend the game for as long as he can so people complain less about updates.
Well, it's technically impossible without completely rewriting the dev's scripts. Why? Because of conditionals. For those that don't understand what a conditional is think: if (this) then (that) else if (this) then (the other) else (do this instead).
So, even if you had every single path/love/like/fucknut/whatever variable set to True, the very first item in the conditional the dev wrote would be the scene or label that is jumped too.... so you'd only get that particular LI scene/label dialogue.
Think about that for more than 2 minutes and you'll see what I'm getting at... the conditional is: one thing
OR else this thing
OR else the other thing
OR else even yet another thing.... it's never
AND "all things".
This is my Crown & Coke version of how conditionals work in code. Take it with a grain of salt but I think it sorts the issue in a nutshell. This is NOT a kinetic written novel... choices have consequences due to conditional code (the if/else if/else statements). To do what you're asking would take someone to remove every single conditional out of all the code and re-write the scripts to flow in an exact way to achieve all LI's and try to fit a storyline..... that's wayyyyy the fuck out of the scope of my mods. It's not my job to write a story... that's on the developer.
Hope that makes sense. Let me know if it doesn't somewhere. Regards.
