Understand correctly. It is easier and faster for us to fix something specific. It is not possible to fix everything badly. It's easier to drop everything and start over. But does he have the right to start over again who does not bring anything to the end. Write more precisely what does not suit you.
Here are a few of my suggestions, which are not new(probably) :
1. Remove thirst and hunger, no one wants to eat while playing adult game, otherwise it gets too complicated. You can leave need to shower and shave, since it is connected to attractivity, so probably affects some sex scenes.
2. Removing eating, you probably rewrite sport and weight calculation, it is up to you, but here things also get too complicated.
3. Navigation in the city is too complicated. Public transport and taxi, and too much locations with different sub-locations. Difficult to remember where you get quests, job, home. Some locations are useless, so cut them. Make transportation transparent, with 1-2 clicks at most.
4. Clothing system is also insane, like wtf, do i need to wash and fix my clothes INGAME? Like i have not enough things to do irl, i still simulate it ingame.
Sure there are more stuff to simplify and i forgot smthg. It is just so many routines to do, to get things(sex) running in game, so i usually give up, and never play longer than few ingame days. (download game, start it, cheat money, buy stuff, become sexy, try some events, end game, delete it).
Best of luck.
