In the MC computer, you can see all scenes available for each girl, their schedule and hints to unlock scenes. I don't think a pdf walkthrough can be any more more didactic.
Mostly true. If love reaches 200, then you get no more hints. Then you just rely on the schedule catch the green events. Redundancy in space hehe
Anyway, I'm down to very last events involving the spaceship. Been there once, can't figure out how to go back or invite a partner.
Edit: FOUND IT
Couple threads back, room right next to the seeder, to call back ship, then 8am pick a partner
