Mechanics:
You have two main goals in this game:
1: Build up relationships with your crew mates
This can be by interacting with them while they are doing something and by talking to them while they walk around
You can see your progress and get hints on what you should do next using the computer in your room
2:Fill the G.A.I.A
This can be done by using the vial on your desk or by interacting with the girls and reaching climax
Once you have seeder fuel you need to take it to the G.A.I.A down in the flight deck and fill it up, this will unlock new things at every 100 you reach
