Not really original as it is based off of Star Wars.

Creative idea, but like CodeBeasty said I don't really see how this is a machine as it fits to be more a minigame?

Lots of commands to do for a setup, but besides that it worked fine.

Not original, based off star wars, was kinda confusing to read about as well.

I like the idea of a customizable race, although doesn't entirely fit in with the theme even though there are "machines" in the game.

Not terribly high as you yourself said it was based off a star wars episode, nor is the concept of racing brand new.
