Interesting way to tackle the social media topic. Misinformation is a pretty big problem on social media, so it's good to see talk about it. It's definitely not a problem that's letting down soon, which is probably why Twitter recently added community notes to their platform, however those are also subject to people griefing them.
I love the fantasy twist on such a modern topic. It's an interesting metaphor, using being a king's advisor and modern monarchy to represent misinformation on social media. The concept of the game sounds very solid, I'm excited to see where you go from here.
