Just stumbled upon Maze Craze Trucker from "Entertaining Games inc". This cartoonishly designed maze game puts you in the driver's seat of a truck and has you racing around town making deliveries and collecting money. The game design is similar to a pac-man game, you view the truck from above , steer it through the maze and avoid the incoming traffic. Each maze level has a money goal that you must meet in a certain time period before advancing to the next map.
You use the accelerometer to control the truck , by tilting left and right you steer and by tilting forward or back you accelerate / brake. You also have a horn button used to clear the road in front of you so you don't collide with other trucks. You can't spam the button because it requires the buildup of air pressure.
