The monsters are engaged in an epic battle between the evil! They are trying to destroy it for good and you have the chance to help them. Use your mouse to click on the green monsters to make them disappear. You can make ramps for the barrels to roll over and push the Evil into the void. But not every monster works the same, the yellow ones will fly if you click on them, the red ones will explode and the gray ones will create a vortex. You can collect the stars to give you more bonus points to your score.
