From Maxwell Stein:
Based off the popular flash game which has received 20,000,000 plays on Facebook and millions of additional plays on the rest of the web, Truck Rush for iPhone is a brand new 40 level game. To move, simply tap the screen down to accelerate. You'll move faster the longer you hold your finger on the screen. To stop moving simply release your finger. Try and move as fast as possible on each level to get a high score but avoid the obstacles that will be coming down to stop you. Mute the game any time with the on screen mute button or pause it to go back to the level select screen and try a different level if you're struggling with one.All new obstacles and 4 seasons exclusive to the new version will give players plenty to challenge themselves with. Your best scores are recorded automatically and you can go back to any level you want at any time.Supports the beautiful crystal clear retina display (960x640) resolution on the iPhone 4. Runs great on all other devices including the iPad as well!
