In order to get through the Metro area, you have to pay attention to the gravity at all times. Use your space bar in order to give your vehicle some thrust. Once you've pressed the space bar, you will need to release it right before you hit the roof. That's pretty much all there is to the game and it sounds easy, but it can get very difficult. This is an interesting take on a genre of games that are filled with all of the same old stuff with different names. This game truly is unique in every single way.
