Some Sim Date games have been made into Harem anime, though the result is usually nothing special due to the removal of sex and the fact that the narrative can no longer focus on any single character.
Five days of the week, the five girls of the ship have a mission to complete. If you take the mission off their hands, it will significantly boost your points with that girl.
You can check your points with any girl by clicking the "Menu" button.
The girl will tell you what you need to complete the mission, but it usually involves going somewhere -- usually a planet or the archive -- and finding something to bring back.
Another way to increase a girl's points is with gifts.
