Things happen during the day, you have to talk to people to collect evidences, and at the end of the day, you take part in a trial to dicuss what happened during the day and try to identify the villain.
Thing is, the trial makes absolutely 0 sense.
For each statement, you can choose if you agree, if you object, try to present evidence or denounce the statement as a distraction.
Simply put, nothing works.
I saved before the trial, tried to spam any of the options with every statement, it always result in a mistake.
This game is like sneezing with broken hands. You know how to do it, but it doesn't work out well.
