Good morning, and thank you so much for playing!
You're absolutely right about the tutorial — adding a few levels that gradually introduce the roles would definitely help ease players in. Unfortunately we didn't have enough time during the challenge to include one, but it's something we'd love to add going forward.
As for the accuse button: that comes down to a small communication gap on our end, sorry about that! The soldiers themselves are clickable — you can select one by clicking their head or their letter. Once a soldier is selected, you can accuse them as the culprit. The role tokens are only there to help you make and test your own hypotheses; they don't need to be assigned correctly (or at all) to proceed.
Thanks again for the feedback really appreciate it! :)
