What is a good way of finding out the serum paths ahead of time, since they seem to be rather precise and peculiar? For example, I was looking through some walkthroughs, and it seems that since I wanted Ava to be attracted to me, she will end up a futanari or free-use, and the actual route to make her submissive to me would be the kissing route, which wouldn't initially seem to be the choice for dominant players.
I kept looking, reading through the John walkthrough, and it seems that even though netorare is not listed under "Genre" (at least at this point), if you don't proceed in a certain way, John ends up dosing you and the others instead of getting dosed, turning everyone into his sexual playthings, INCLUDING YOU.
Regardless of what the game says at the beginning, it seems there are PLENTY of wrong ways to play, and there are not walkthroughs for every character, much less complete walkthroughs. Since I have to wait often numerous days between dosings, there doesn't seem to be any way to correct character paths other than just reloading, and no way to see what path I'm on until (according to the walkthroughs I've found so far) my stepmother is banging every guy she sees, my stepsister is banging dogs, and I'm just another member of the local NTR antagonist's harem.
This game REALLY needs built-in walkthroughs for all characters, because while I understand appealing to different people's fetishes, it seems far too easy to get locked into an undesired path, some of which seemingly throw off gameplay for the rest of the playthrough.
