It did indeed take me a second to understand how this game worked. Without many moving animations, I actually thought my game was bugged.
But, after about 8 rounds or so, I finally understood that we're going around in a circle and shooting ourselves/each other. It's a minimal game, sure, but by the end (round 28), I found myself feeling shots of anxiety whenever I clicked the "pull the trigger" button haha. Loved that! I haven't felt that feeling in almost any of the other games I've played.
