Short Yet Comical
I would say 8.5, But as I cannot give a .5, I round it up, all the more better for you.
It was great, short, satrical comedy, with the all the clasical puns in there.
I once thought of a slug made of metal, when I saw the game Metal Slug.
I agree with punx6901, That you should definatly make it a bit longer, Maybe chop between 2 scenes after the slug in the superhero place, with the slug going to the video arcade, and beating "Metal Slug" on "Uber Super Hard" Difficulty, And then a scene with annoyed superhero wannabes who cant get a name becuase of copyright laws.
Thats just my 2 cents. Bye.
Keep up the good work.
