It seems like almost everyone is having trouble with the basics of controlling the game and progressing, which is entirely my own fault. Since I made the game I knew how to control it but that doesn't really translate to anyone who didn't develop the game. I am sorry about that and am already trying to change this for the better.
There is a lot of talk about the grind and the reason for that is I was trying to keep things as "realistic" as I could but it is just too slow as is so if that has turned people away it will be different next update.
Until then here is some stuff which will hopefully help you out
To interact with anything in the game get close to it and look in it's direction and when you see a highlight around the object or character press either E on the keyboard or the left mouse button
Sleeping in the bed will advance time by an hour
Using the computer lets you see your progress and if you click on one of the characters you can get hints at what to do next to advance their story
The very first thing you want to do is use the vial on the desk in your room to collect seeder fuel, once you have done this you take it to the flight deck and place it into the Seeder (first room on the left). Once you get it to 100 you will get an event and Adrianna will drop her level 2 card in the medbay, this lets you access a lot more of the games content.
The next step is to grow your relationships with the girls
If you interact with them as they are walking around the ship you will get all the dialogue options for that character. This is when you can give Adrianna the wine and also if you talk to Natasha after taking her wine she will start to hide bottles around the ship so there is always wine available to you
If you interact with the girls when they are doing something you will start an interaction event. If your relationship with that girl is high enough some of these will lead to the games more adult content
the current caps for the game are: 250 seeder fuel, Adrianna love 60, Katherine love 40, Natasha love 40
Everything in the screenshots is in the game currently, it's just that I did a terrible job of explaining how anything works
Expect an update to try and address all these issues in the next few weeks
