I have been playing Hulk Smash.

The game is rather compelling. The game play begins in a major city that remains unidentified with several well-architected and high-end design inspired buildings. The object of the game is to climb and smash the buildings one by one on both sides until they collapse.
The game is not for the faint of heart. By the second level, you are not only trying to beat the clock but also avoiding the military vehicles that enter on either side of the screen that shoot at you. You'll need both cunning reflexes and meticulous strategic planning to avoid being hit and anticipating which side of the screen the vehicle will appear next. With good strategy and sufficient luck, you will be able to smash the vehicles.
The game can be demanding on the casual user, tying the user down to their seat with unparalleled addiction never seen before. If you're not careful, days will seem like minutes as time rushes by while you continue your quest.
I give this game 0 out of a billion stars because this entire review was meant to waste your time.
