I liked the Halloween party overall, but I thought the interlude was kind of a waste of time. Zoey is not the MC. There is minimal reason for me to really care much about her based on the previous episodes and the interlude doesn't change any of that. It just makes me spend a lot of time skipping through irrelevant scenes that could have better focused on the story for the MC. At least you weren't forced to watch her fuck someone else during the interlude so she doesn't cheat on MC, just leaves him hanging.
The main complaint I have with the halloween party is that it doesn't really seem like there are any choices that make any difference. Your options are pretty much all predetermined by the save you imported from the previous episode. So if we're going to have a big party where your choices don't matter, it would have been nice if there were more sex scenes. Most of the sex scenes come at the end and require you to pick 1 or 2 girls. On the chick path where you picked either Jill, Bella, Maya, or Josey that might make sense. On the DIK path it would make more sense for MC to play the field at the party.
The way it's currently set up it seems like you pretty much have to have played through the previous episode enough times to have a save focused on each individual possible ending if you want to see all of the content in the current episode. Fortunately there's a link in the OP where someone made saves available that do just that, but I would find it rather annoying without that. Especially since this episode is broken if you used a cheat mod in the previous episode.
