For this assignment, our team decided to go with the concept of a platformer where a cat is searching for its owner.  As this was for a game systems class, a large part of our focus was on developing the game loops that would occur.  The predominant system is cat's need for stamina which is used every time it jumps, and is replenished when it collides with a treat.  Additional systems include a progression system for the platforms which become trickier to traverse as time goes, and sentimental items which fall from the sky and give the player temporary bonuses.
