Ok, I don't think I've ever seen anyone report this.
I was casually playing Yume Nikki, and I decided to give uboa a visit.
So I went to ponikos room and got Uboa on second attempt.
Keep note I was playing this while talking on skype so F4.
And so the people I was talking on skype have mostly not played/heard of Yume Nikki, so I decided to take screenshots as I played.
Got Uboa, touched Uboa, walked around in Uboas world, all normal.
After minimizing the game, and opening it again, I notice I'm standing in Maddy's room.
At this point I was fucking freaked out, thinking the game might have started new game. [spoiler]I was staning in the middle of her room, where you start the game when you well, start the game[/spoiler]Post too long. Click here to view the full text.
