Not bad, although it does have a few of the standard problems that annoy me in the genre (instant bad end choices which basically amount to two buttons, one of which is "keep playing", the other of which is "stop playing"). Also, Mom had better have a REAL good reason for storming into the restaurant and just saying "everyone out, leave your meals here, we're getting drunk instead because I'm pissed off" and then not saying why, because that's serious bitch material.
Also, I approve of the early adoption of at least dream sequence sex. A lot of these games move so slowly that they're constantly cock-teasing their players: "version 0.2, you can spy on your sister in the shower; version 0.3, you can grope your mother while she sleeps; version 0.4, your sister gets drunk and gives you an accidental buttjob; keep supporting my patreon, guys, because there won't be any actual SEX until version 0.9!" Don't be like that. We all know what we're here for, and it's not 10 months of blue balls. Also, I like the Pussy; the cockblocking in the dream was hilarious, if (clearly intentionally) frustrating.
