Game: Cardiac Castle
Cardiac Castle is a game for the iPhone. It is a vertically scrolling pursuit game, where you, the gamer, must escape from the monsters chasing you through the dungeons of Cardiac Castle. A variety of obstacles stand in your way, but these can also be used to your advantage, as they are just as deadly to your pursuers as they are to you. As you progress, more and more monsters and obstacles will spawn, but don't panic, because the monsters can smell your fear! Cardiac Castle uses the iPhone's built in camera to measure your pulse and determine the speed at which your heart is beating. If you panic, your heart will speed up, and the game will react to this by spawning more monsters to thwart you. The object of the game is to progress as far as possible through the endless dungeon before meeting your inevitable demise.
The Truth is Out There: Some external real world element, such as weather, time of the day, etc, affects gameplay. It MUST affect gameplay and can’t be only a scenario element.
No cheating (please): The game system relies on willing player participation to enforce the rules of the game world (e.g., hold your breath, close your eyes, etc.).
