A nice start,
But I really recommend getting help from an artist. Some of the graphics are a tad too oldschool and are unappreciated by newer users. Also, a larger screen size is nice too, I find myself always clanking into walls that are too close together. You should also try to ad things such as power ups (lifes, fuel ((With fuel power ups it'll give a boost of fuel to keep going, I know it returns.)) etc.) Overall, a nice start, but not a very good game.
