Incredible match to the theme. Neat idea to take part of the action outside of the game.
The balance issue I have is that the guerrilla gorilla isn't informed of that before the dances. That encourages players to cheat before they even know if they're the impostor or not. A quick pre-round before the dances may have been required to deal with that, though it would have made the game clunkier.
Great music choice, and I LOVED the dance animations. Very cool!
