This game really needs a progress tracker for the girls so you can see their stats and if there's anything more to be done with each girl etc. 

There are a lot of girls, which is great and they are great, but it'd make things so much easier to be able to know where things are with them without interacting with them considering the limited number of actions we can take per day. Also, it'd help to learn the girls names which is handy when you need to talk to specific people to progress certain quests

Also a personal stat tracker and inventory system would be great. Just increased my strength for the first time, and it'd be nice to be able to see my stats. Also knowing what items we have would be helpful. 

I know all this is probably a huge amount of work for you, would it would a huge quality of life improvement for the game.

A better interface is planned, but for now, all of that is listed in the "Stats" page that you can get to with a button on the quick menu (bottom of the screen).
