Drive your mighty bulldozer through the green field and destroy any buildings you find on your way. Use your mouse to move your iron ball and hit the building with as much force as you can. As you proceed to higher levels, you will upgrade your bulldozer with items like hooks and bigger iron balls. If your bulldozer hits a building that has not been destroyed, the game will be over. Complete the required number of buildings to destroy to proceed to the next level. You will get a bonus score if you destroy a building with only one hit. Happy crushing!
