I love your games. This one seems like it will be very solid. I like the idea of replay ability for new routes/endings (so long as the relevant scenes are saved, like they were with you last few games). A few suggestions:
1. As a quality of life thing, if possible, is to balance some of the stochastic elements more in favor of the player *eg making the opponent slightly more likely to have a bad hand at a card game, over or underguessing in black jack, or making it so specific item drops are more common if they're critical items, etc.* Sometimes those can ruin the experience if you have to replay a specific game a bunch of times to get a specific outcome. I like the minigames from an immersion perspective.
2. Humor in the storyline is good (eg. including events with unexpected causes and effects, characters lying in a very obvious way and getting caught but the outcome is innocent, unbelievably dumb behavior/characters, hypocritical behavior generally). I notice you do this subtly sometimes and can tell you have a good sense of humor. Lean into it more.
3. Seems like you have this planned, but when breaking into sister's or mother's phone, option to find video of "liason" with another guy while you were working your magic with a different character (or perhaps while you were asleep, etc.). Or texts exchanged reflecting the phone owner's feelings for their brother/son.
Keep up the good work!
