Haha, funny thing is, this is the exact same concept we had in mind when brainstorming ideas for the theme! Our idea was that you’d see servants walking into the throne room, and you had to watch them closely to see if they added poison to the food. If you caught them, you could make the servant eat the food themselves. It would require a bit more animation, but at least it gives you something concrete to base your trust on. If you fail, the king dies instantly. Oh, and by the way, our game still revolves around a king, but in our case, it's a Pharaoh!
