This is a snake game which is navigated by a joystick. We have also used a pulse sensor to tweak the game. The pulse sensor makes the screen change color depending on your heartbeat. The moment when your heart beats, is the moment when the snake is visible. When your heart does not beat, you will not be able to see the snake, and the game will be quite hard to control. This means that you will need to get a high pulse to get a good score in this game.
The problem with this game is that the pulse sensor is not reliable since it sometimes register a pulse signal whenever it wants to.
