I checked out this game awhile back and I did not really enjoy playing it. The gameplay has only one style. That is, you, the dog, catch the eggs and get the highest score. At first the eggs move slowly, but as you progress further, they move faster and you would have to catch them all in order not to lose a life. Around 100 eggs will net you an added bonus life.
The game similarly looks the same as in game & watch games, though because this is an iTouch game, you would have to tilt your iTouch to move the dog in either of the four positions. This can be a good game for a short while, but not a long lasting game that will get you hooked for hours in my opinion.
