Short and Simple
Start the car by clicking on objects until you find all the pieces you need to start it. The concept of the game was very simple, and it didn't take much to find all the pieces needed to start the car (although some items were hidden decently enough that I had to come back a second time).
The 3D art wasn't overly complex, although it seems to show more effort that just throwing in 2D drawings of equal value. Could have used some sound, possibly some music to fill the silence.
Plenty of games like this, however, and it doesn't seem to have anything special to make it stand out from the rest of them.
