The objective of the game is to drive as fast and to get safely to the nearest medical center so that you can save the life of an injured man. Use up and down to move forward or backward and left and right to turn on the hydraulics. In case you flip over, you can reset the game by pressing R.
You’ll have to pass mountains to get to your destination. Don’t worry about the first level as it is just a snap, the real challenge is the subsequent levels. The challenge gets harder and harder from then on. One last thing, there is a walk-through which can help you finish the game.
