Wow, I seem to always end up doing some bug/typo reports for Silk's games.
Stimulation, Gambling Life, Under House Arrest, and now Oath of Loyalty.
---------------
Sure there are small continuation errors (like poor people not being surprised at person's being rich), minor forced story (inviting Jane to the party instead of Angela), minor forced sex outcomes (sooner or later you have sex with Jane, Daniela, watch the Mother), minor scenes showing a different character with an open mouth than whom is talking (I assume it is just to save on renders and people are talking over each other, or from camera position), overall the game is shaping up well and the story is moving along.
I am surprised there are 2 paths with Angela/Jane, as far as I can tell all other sex scenes other than spy on aunt are forced. Why not just have both the dates with Jane and Angela so players can get to know them both instead of being an either/or? If you are going to end up with Jane for the moment, seems like it is extra work separating them for no real reason.
Now that I remember Silk did UHA, I seem to notice a pattern in his depiction of some cousins, always wanting to get high/drunk/have a good time.

Only 5 gripes really with the game.
Personalities of girls: Like the date between MC and Jane/Angela most of the language is reused, thus making both characters less. It would be nice to have their personalities more stand apart. No I don't mean making one subservient or the other a tsundere. Just different word choices, different jokes, etc.
MC has a personality and that is fine, but sometimes it flips. What I mean is when the Detective came. Previous to her the MC is all about calling police, and being nice. However with her he is combative, and yes the situation had her being that way first. Antagonizing an officer isn't something "good" people do out of nowhere. "What's it to you? It's a free country ain't it?" and the "Maybe if you cops did something" line isn't someone who respects authority, since this is his first shown meeting with police and he has yet to fully understand his family, he should probably be more polite in his talking.
Sex scenes. I understand these are probably the hardest on your GFX card. These scenes would be nicer to have full penetration rather than just the first 2 inches of his penis. The where to cum scene would also be nicer to be its own separate small movie and showing it instead of just a boom it's there.
Sounds: The moans... are bad, I am fine with moans, but they really need to be longer instead of almost instant loops, and audio normalized to both be audible but also not blow out ears, except for Jane's Second sex scene first moan which I thought was that sound in movies when they start a radar ping. Also the reuse of the same girl laugh between both girls, it would be nicer to know they might have a different voice.
Faces: A lot of the characters have slight uncanniness to their faces. Sofia, Julia, Sal, Paulie, MC all look fine, the rest of the cast so far just slightly odd.
-------------------
I get the other poster's critique on Jane not being surprised. It is pretty common to know someone is rich, but different to see it. I used to deliver stuff, had to go to the rich neighborhood and most of the houses were nice, then you had a few which you thought were hotels because of how enormous they were and finally castles, fucking literal castles. They have indoor and outdoor pools next to their saunas/Jacuzzis/steam rooms. Even if you understand someone is rich it still catches you off guard to see it.
Also I slightly get the MC being hypocritical on him getting blasted out of his mind and banging his cousin, then complaining about his mom drinking. Yes her always drinking is bad, but at that moment MC should maybe be a bit retrospective
The club scene with the girls does feel like it should have had more people in the background especially since MC mentions it will be bumping in a few hours, then a few hours pass.
I don't think I got to check all the text, so not sure if any other errors.
I would slightly request a "book" of details on the storyboard, this would contain all previous information like the stuff you learn from the prologue, who is dead, what a stunard is, etc. Since this game will come out in parts some players may come back after multiple updates and have no clue who or what is going on. What is a stunard? yeah you mentioned it in chapter 1, but someone coming back after 6 months won't remember that.
