A couple suggestions I came up with from playing the game:
1) Perhaps make the playable time longer or even infinite
2) If you're not close with a woman and she's in the W.C. then you speak to her while being in there she'll get mad or disgusted by you
3) Possible ways to make income as for some reason I am not able to go to the places that can generate income so unless that's a bug I suggest adding more ways perhaps from your phone
4) Add more to the personality traits, so if a woman is married but has a slutty personality she'll easily cheat even with low love influence
5) Add stats that can help with certain tasks, you could go for the basic "Strength" "Charm" "Intelligence" and each stat would attract different types of women, such as if you have high strength and are at the gym or pub you'll gain bonus influence while being in those areas, if you have charm and at the university (besides the library) or in their home or your home also gain bonus influence and so on
6) The "Ask if want sex for money" should be implemented but you're sex knowledge needs to be up, while on the topic of sex knowledge if you've read their personality and have maxed out sex knowledge, while having sex the options will show you a hint in which will gain the most pleasure
7) Lastly, fix the grammar a bit and it should be a solid game once the art style improves and some of these suggestions are added
