At the very start with those square configurations of eight people(?), the way the game's physics cause them to turn and block you if you try to enter the center, that was pretty powerful for just a bunch of squares moving around.
Thank you for noticing! It really means something to me that someone is paying attention to such a detail and playing the game in a thoughtful way, that's the way it is meant to be played. So thanks for giving it a try!
