Few suggestion:
- You should make girls be in contact with MC even if they are going to be older that 50 years. Leave them be as they are, don't remove them from game, instead, try to implement an ending of life scenario for a girl.
For example, You can implement illness stat starting from age 50, and you can add for example few different scenarios of loosing a girl etc. It will also lead to MS paying some medical examinations, meds, treatments etc, because it is pointless to have so much cash but we can't use it.
- Make girls more different. Girls are repeating during gameplay, make them more tough to conquer, some of them you can make easy to conquer, tie an stats for MC, like Welth, Health, Personality matching, clothing etc.
- Portrait pictures should match video picture of girls, at least near close to look like they self, or add more different videos for each type of girl and age. More differ the girls more interesting is to play, more similar girls are between portrait and video, more interesting will be.
- try to fit background pictures to fit with buttons in one page (avoid scrolling down for buttons), maybe implement side menu for some vhoices or whatever. After a while of playing, it starts to be annoying when I have to scroll down every time in every menu to search for button. So, common resolution is 1920x1080, find some balance to fit background image and buttons in that resolution.
Anyway, game is pretty much good, i can give it a score 8.5 of 10 right now
