The main reason I mentioned it is that personally, I dislike playing games with a walk-through open. I want to immerse myself in the game and just play, not follow someone else's guide.You really need to read the walkthrough, I completed the game to end of latest update. Eric has never touched anyone but Ann, and he never will. If Eric so much as shook hands with anyone but Ann, in your game, you did something wrong. You can take the long path(friend or enemy) to get rid of Eric. If you are enemy of Eric, 16/17 is all opportunities for now, you just need to complete them. There is always a % chance Alice will not keep her promise. Save just before you need her to keep it, and go back if she does not. Repeat a few times till you get it.
PS: Don't let worm face worry you, just get rid of him, in the next update.
IMO the in game context and/or hint system should be good enough that you can figure out what to do without needing a walk-through. Maybe that's just me. For most of the opportunities it already is that way but there's a few of them that I haven't been able to figure out so I think there's a few that could use some tweaks to make it more clear what to do.
Presumably that will get updated as he adds new stuff anyway so I'm not too worried about it. In my case Lisa and Kira's content is done and I've gotten far enough to give Alice the bodysuit for her blog, get her to sleep naked, massage her thighs/pussy, and get her to lick his dick after clubbing. So I think I've seen most of her stuff but the party girl, alpha, and blog achievements still don't say they're done for some reason. From the teaser renders I've seen before this latest update came out though, I've seen all of them in my game.
