I really like this game and it still has a lot of potential to grow, but I have a couple MAJOR complaints about the UI that would really make the game a lot more enjoyable if they were fixed:
1. The background color(s), especially the green with the white hues used e.g outside of the apartment often make it really hard to read the Text. I would recommend to choose a different Font color that is distinguishable on all Backgrounds, or alternatively change some of the Backgrounds (though that would probably be a little more work, so font color would be my Recommendation)
2. I would also in General be thinking about a smaller Font size, as the current size leads to a lot of tedious down-scrolling to get to "continue" buttons or to get to the Button to get outside or inside your Apartment, e.g..
(IDK if im the only one who has this issue, and If this is the case, feel free to ignore this comment)
3.: Make the images in the gallery and the Walkthrough Sections smaller! I've spent so much time mindlessly scrolling, especially in the Walkthrough Section...
Also, for the gallery I would recommend adding sub-menus for different Girls, once again to increase usability
This game has potential and is already a great project, don't let it be dragged down by such minor annoyances anymore
