This little game is fun. It's also challenging...you've got to get the black, evil cars out of the picture...while you keep the police cars, fire trucks and ambulances in the picture...you need to stop the vehicles in the green area. There are 20 regular levels. Get through those then go back and re-do the levels that are starred for the the opportunity to take on the challenges in levels 21-35, the mega levels. How many levels can you make it through? Think, strategize and have fun! You'll be victorious when you play Vehicles!
