A rowing game where you have to make sure not to over exert your heart. Each paddle is controlled by an individual button, so play with 2, 3 or 4 players at once.
Backwards: One or more aspects of the game works the opposite as would normally be expected: maybe the controller is reversed (left is right, right is left), maybe you win lives every time you die, maybe it scrolls to the left and your character moonwalks.
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.
Approved for All Audiences: The game must not show any violence, not even cartoonish. Stepping on living mushrooms is off the list, as is killing any type of enemies, not even undead, though we know they’re already dead…
