My apologies for being negative, but after reading comments here, being stuck in my game and taking a look at your code, I think the structure of the game is going to present a lot of trouble for you and players that don't want a harem experience. If certain interactions require X amount of RS points to trigger (and the game comes to dead stop and won't progress), yet the previous choices in the game give the player the option of not scoring points or even acquiring negative values, then that's not a choice at all. Requiring players to replay scenes in order to finally achieve enough RS points is...well, I don't think I've ran across a game coded like this and am having difficulty understanding the logic of doing so.
I predict you will be spending much time on here helping players past these scenes, especially given that many won't read previous posts.
