Super easy to understand and jump into immediately. Good execution. Not super tightly fit to the jam theme.
The most interesting aspect of rock-paper-scissors like guessing systems is trying to understand and outthink a human opponent. So with bots, they need to have some sort of human tendencies to make this more than just a random guessing game. If they do have tendencies and habits, it's hard to associate playing patterns with the other players because it's not easy to tell who picked what card.
Overall, really solid entry and one of the easiest games to jump right into.
