There are 15 little stars scattered all around the image depicting Tom and Jerry in different situations. The objective of the game is to find all the stars with the help of magnifying glass. Time spent playing is measured but it really doesn't make any difference whether you spent only 5 minutes or 5 hours playing. Unfortunately the user interface seems semi-finished so there's no elegant way to pause the game or to return to the beginning. There's no level selection screen neither. Anyway, if you don't expect too much of this 'simple star collector' it should be a decent time waster, at least for a while, before you realize it started to become repetitive.
