This game doesn't have any time limit, eventually you will max out everything.
At weekend you can swap your part time job.
First you have Bartender (Mondey, Wednesday, Friday) and Delivery (Tuesday, Thursday) aviable. Later, when you have enough intellect, Security (Wednesday work only) open up.
Intellect and Strength has threshold at very low and after that you get double (2 -> 4) stat for each time. This will help a lot to reach 88 stat, which is maximum. After 88 you only get slightly more money each week (Strength) and living costs goes down (Intellect).
Intellect as stat open up new store options, lower your weekly living costs and it also allow player to see girl preferences.
Strength as stat increase weekly income and increase actions. At first it's easy to mix up actions into turns. Turns is how many times you can interract with girl in non-H scene and actions is how many times you can interract with girl in H scene. Interractable H scenes are mostly groping on different areas.
Money become trivial very fast, but at begining you want to forget buying anything from store, until you have enough intellect to open up Conveniences tab in store. These household items are permanent purchase and they will increase all girls affection on each turn (remember, action is only in H scenes) you interract with them.
Sadly there is only few random special events and no weekend dating with girls.
