Below is the original details:

A bumper car game built using XNA and C#. Must look outstanding and provide all source code/content.

The theme of this game is bumper cars (the kind found at the carnival).

Basic requirements:

Full screen or windowed play

Support for 1 player

User chooses Easy, Medium, or Hard at beginning of game play
Easy has 3 opponents which are not difficult
Medium has 6 opponents which are somewhat challenging
Hard has 8 opponents which are quite challenging
Each difficulty level has a different background (bumper car area) theme

User is allowed to choose one of 4 bumper car styles to play with

User has health of 10 bars, and loses one bar each time another player hits them on the side or back (displayed at top left of screen)
When all bars are gone, the user loses a life and the bumper car appears as new in the center of the level

User starts out with 3 lives (displayed at top of screen as well)
When all lives are gone, the game is over, and the user is presented with their score and a chance to enter their initials for the top 10 high scores.

Score is displayed at top, the user gains points by hitting other players, as well as a time bonus if other bumper cars are eliminated before the time runs out.

Game has basic sound effects for hitting other players, being hit, start of level, and background midi.mp3 music

Upon winning or losing the user should be presented with an option to play again.

Most of all, this needs to be fun, and easy to use. Thanks.
