Game: Blind Pulse
A small 1st person multiplayer arena fighter. The twist: you can change between being in one of two dimensions, you will only see opponents who are in the same dimension as you are. Being in one of the dimensions will increase your heartbeat, being in the other will decrease your heartbeat. As opposed to our initial vision of this game, the heartbeat does not affect gameplay.
More the Merrier: The game is a competitive or cooperative multiplayer "party game" (i.e., based on minigames, humor, 4+ players, audience engagement, etc.), meant for one screen or more.
