Short, sweet and deliciously simple. I love the motifs here and the open-endedness encourages play from both sides of the referee screen. I'd love to see this expanded upon in the future, maybe with a chessboard element but that's just because I love a good external component in my ttrpgs. Still, the information for the referee and the multiple ways players can tackle this (along with the time constraint) makes for a great mission that is a great contender for convention play.
