The interface is ineffectively designed. The car lot screen should have a highlighting car choice, and should have a next button to advance, preferably on the lower right corner, as is common among games. The back button should be on the left of the screen to more closely replicate a left-right progression, where right is forward, and left is backwards (seen in books, platformers, and other media).
This game is a lot better then helicopter. The music is slightly cool, the graphics are better, the obstacles aren't generated completely randomly like in helicopter. I liiiike this game. 5/5
