Guzzler

You are Greedy Guzzler and your task is to move about various top view mazes shown on the whole screen to collect keys which will enable you to open a food cell and eat all the food in it. Once you have cleared a food cell you become fat and you are unable to move through thin gaps in the maze. Moving about the border of the maze is Deflator Dennis and when you touch him then you are thin again. Touch him while thin though and you lose a life.
