New Super Mario Bros. U (original)/Beta Elements

This game was originally going to be called Super Mario II for the Wii and Beta Wii U, which discontinued when the Wii U came out. Miles "Tails" Prower was going to appear in the game but was taken out for no reason. Hard Mode was going to be an option in the game, but was taken out due to making the game easier. You started with 4 lives instead of 6. A very hard glitch called "the Mario way" was also made but was taken out and still remains in the code.
