The art is cool, and the plot is intriguing. I couldn't find the "Confront" button that the others mention. However, it's so easy to click "Accuse". You can accuse as soon as you have one suspect and one weapon, but if you miss one piece of dialogue, it seems like you miss "Confront" entirely. That's obviously what happened to me. It's a pity, because I was really getting interested in the story, and I just got stuck like many of the others in the comments here. Maybe I'll come back to it another day!
