Maybe you should try to separate the story and the rules of the game more. Like a note on the side talking about the story and another about how to find out who the accomplice is?
Wow, what a brilliant yet simple idea! I'm surprised it didn't occur to me earlier. Working under GameJam time constraints meant we overlooked some of these details. We'll definitely add this to our Todo list once the evaluation period ends. To keep things fair for all participants, we've decided to hold off on adding or changing any features for now. Thank you so much for this valuable suggestion!
