I actually kind of agree. I think the pacing content-wise seems alright, but if you look at the time that has passed AND the progression of things with the family, it does seem all happens a bit fast.
Maybe it wouldn't have been a bad idea to move some things to another day and make more days in general.
Not the content nor the size of the updates is wrong, it's just the timeline that seems a bit short.
To me it's exactly the opposite, the pacing feels just right. Those kind of things happen fast, you either fucked up in the head enough to have sexual feelings towards your own family or you don't, it's that simple, all it needs is a little push for it to snowball downhills.
They've known each other for years and the feelings were already being nurtured in the back of their heads, we as players are doing that push, we just didn't get to see much of the build up. The only character that actually feels like we're corrupting is Jenna, with her I agree things are moving a bit too fast, specially with her being a complete shut-in.
About the game: Great update, Monica is my favorite but she kinda disappeared this update, the dynamics between Katie and the MC is just great.
