Thanks, I only reached two endings (using some save), one on the sex toy on the train, and one as slave to the Director (with my surprise, because I had started dating Taro).For the pool scene you need to get on the Bully Path. That is by helping the Student that is getting bullied, and winning the fight against the two bullies.
Bully's to turn Alona into their plaything and so on.
By chance (not on purpose) I lost the first fight with the bully's, but then she just said something like "I don't want to go close to them", so I guess for the bully path, I would need to insist she tries to go to the bully.
I also guess the gardener path is something that can start only after the night you inspect the school, if you do not kill the gardener - that was the first time he did not just say "don't bother me" - and continue interacting with him.
Though in both cases I reached the point where the director would make her permanent, and even if I had 5/5 on the drugs and I had seen the room with the code, I still got immediately the end game.
If I understand well, the logic is that for each of the paths, you can go through the steps losing or doing more "stuff", and that only reduces her "alertness", but if you go to the last step of any of those paths (train, black underwear and punishment by the Director, etc.), then you when you get to 100 "school points" (don't recall the name) by doing things at school (or losing interactions at school) and the Director appoints you, instead of getting the code for the door, you get the ending, even if you have 5/5 on the drugs and have already discovered the hidden door.
Right ? Or you really must have done nothing all the time ?
Yes, it is not as simple as it may seem at first, I don't like RPMG games in general, it could be said it has a lot of "grinding", and I definitively strongly dislike "scat" (I think that is the term). But I like the game, in reality the "grinding" is not really "griding", because you get to new (lewd ) content often enough. I would change a couple of things, but I'd rather try to concretise a couple of ideas for a different game.
