You are the mountain maniac who is furiously angry. Smash your hammer on the mountain top to throw boulders over the city. As the boulder falls from the mountain, it crushes what ever comes in its way. You can control the boulder with the arrow keys to direct it to certain places to achieve maximum damage. You have to make a certain amount of damage to the city to complete the mission. The police will chase you to the mountain top and you will have to crush them too with your hammer. The more damage you make, the more will be your high score.
