Shame it's been so long without an update, but not having stuff like exteriors set up can kinda paint you into a corner, so hopefully it will be worth it.
The characters are great. Ash is mostly anticipation rn, because nice people with thick emotional walls tend to become the most needy and affectionate once you break through them, but she's attractive and punk chicks are probably my favourite aesthetic. Seeing Emily eating a meal once is enough to fall in love with her, and the honey badger vibes are great. Samantha isn't super my type, but she's definitely hot. Idk if you're guaranteed to run into the scene with Piper, although it would be hard to write it as optional, but I'm hoping she'll get a basement room in the house. The charity is self-funded, so it's not like they're obligated to only take wards from the state. She also needs help turning her life around. I know little about her character, but... I feel like she would be useful in developing both Ash and Em in interactions.
I feel like the creator sometimes makes life harder for themselves for no reason. Most of the choices don't matter at all except perhaps a few lines of dialogue, but some still are annoying to address the multiple possibilities in the future. For the most part there's an optimal way of doing things, and there were a number of times where there were flashbacks and such that showed shit that didn't happen when I didn't follow it. "Honest and guileless" as a general rule basically gets you most things, and the game basically doesn't punish you for being a horndog either, so the relevant choices are extremely few. Either you're interested or not, you don't need to put in thought to their temperament.
Other than a toggle choice at the beginning for if you're not interested, the only other choice that isn't between two characters that might matter is a one time toggle on whether you're going to be a complete or partial pervert in your interactions with the character... and the game will only punish you, including in affection, if you avoid being too perverted. The MC's own boundaries are enough. So I'd cut a large number of branching choices that don't matter from the game to be replaced with linear segments. There are a couple things you need to balance, but they're Emily's affection, corruption, and Ashley. These are pretty much "major decisions" only. After looking at the walkthrough, the actual choice seems to be between Emily LP and CP for both of them. CP can substitute LP for basically all of Emily's checks. So it makes sense to do a solo Emily lovey-dovey run for that specific content and just be horny as a rule in your main run. So yeah, I would make things easier on myself by cutting almost all the choices out of the game.
The name corruption points isn't exactly accurate, the only character with affection points is Emily. For the main girls, it's how much they're interested and comfortable with you as a man rather than just something like a family member. Frankly, I would probably roll both into Relationship Points and make your approach with Emily a major choice early on that decides many things for you later. It's my personality that I can't help but think about how I would do something if I was making something, and I got a headache trying to imagine supporting all the meaningless branches in the story properly. It's also my personality that trying to hold in opinions feels like holding in an overdue shit. So yeah, excuse the nosiness please.
