1. Ask any girl to move in together, you will get a quest to buy a house.
2. If she's searching for sth in the grass next to the locked gated - the object is to the right of her. Go slowly, crouch - it's a gold pin.
3. Probably in future version/never.
2-Ok, might have been bugged then, I always see her on the map, but each time I went to the house, I never saw her.
I finished the game anyway and am a little disappointed, a lot of things aren't taken into account.
3Girls asked me out, I accepted the 3, managed to unlock the polyamorous relationship to 2.
When I had to choose a loved one for the ending, only one other, that was in the polyamorous relationship reacted as if it was betrayal... the other didn't flinch.
With how much content that seems missing is left to be done on the game, the fact they announced they would stop monthly update to focus on a final version is worrying, it smells like a rushed development to just polish what's already there and dump everything else.
