The touch screen is perfect for this because you simply have to touch it to mimic the head-pounding action. The Lite version gives you fifteen seconds to hit as many as you can, giving you a score afterwards. It does not really allow for any opportunities for a change in settings, such as a change in difficulty level, game time, or score cataloguing. These are all elements that are left to the full version of the game, which costs $2.99. This version offers several levels of difficulty, eight cartoon characters to choose from, and a variety of setting changes.
