I got some feedback that gameplay is a bit confusing. To help with that, I've updated description of the game to clarify objective & gameplay.
Basically you are a detective in an alien world and you have to investigate cases based on information you get from talking to the suspects, observing how they look like, taking witness statements, and checking evidence. You have to make the suspect, who you think did the crime, give a confession so that you can charge them for their crimes. They may lie, so you can force them by using tools to make them tell you the truth.
I understand it is missing a lot of polish and is sometimes confusing, after the voting period ends I will deploy an update to fix that issue.
