Oh this is fun. It's not complicated to try to think through just one turn of Uno, since it's such a simple game. But with the time pressure this becomes a fun system of trying to go fast without overthinking.
It would be cool to see the other Uno cards (skip, draw 2, and especially on-brand for this jam, reverse), but that does make it a bit more complicated, both in terms of the two players' AI and what you have to think through as the card.
