This game is great.
Cute artstyle. Nice characters. And good backgrounds. And very great music.
I really like the plot. The investigation. Plot twists. Funny situation. It all makes it great.
But I have question. I think I haven't done anything bad but I still got "bad ending". As you said, game have three endings... And I really don't know what I did wrong. Would you mind giving me few hints or maybe giving a little (or not little ;) ) tutorial. I mean, to let us know how to get good ending and the 3rd (neutral?) ending.
