Go through the gates to get more bulldozers and reach the goal!
If you blow away the characters in the middle of the stage, you will get a reward when you clear the stage.
The more bulldozers you have, the easier it will be to blow away the characters, so lets blow away the characters with lots of bulldozers!
Enemy bulldozers will appear at the goal, so increase the number of bulldozers to advance to the goal and defeat the enemy bulldozers!
