This game is severely lacking polished relationship mechanics. That should be what the gameplay look be around, like any girl protagonist game to exist. Protagonist has no feelings herself, whatever she does, it's like she's a doll with no reactions. Relationship, cheating, jealousy, etc, these should affect/corrupt the protagonist. Currently, money is really the only thing stopping you from doing anything. I understand the idea is to create a sandbox where anything can be done. But there's a difference between a sandbox filled with feelingless dolls or sandbox filled with realistic reacting NPCs.
- No corruption mechanics. I would argue that slowly unlocking the daring things (like cheating in a relationship, prostitution etc) will only improve this game, add in some thoughts of the protagonist on what she does and it gets MUCH better.
- How you dress, people don't really react. I mean, what is your partner supposed to think about you going out looking like a hooker? People in the city? Maybe a reputation system?
- Talking to people , it's like seeing all options once and knowing you're done seeing what there's to see.
This is just a constructive criticism, it's your game and vision at the end of the day.
