How scoring works
Each round, there's a shooter and a defender. Both pick a direction. If the directions match, the shooter wins that round and their streak goes up by 1 (the other player's streak resets).
If the directions don't match, nobody scores, all streaks reset to 0, and the turn passes to the other player. First to hit the chosen streak wins the game.
