XML Actionscript3 MAZE

The project, a game, consists in creating a maze randomly through code, with ActionScript3 (Flash CS6 compatible file, preferably) , in which the user has to control a player (with the arrow keys) to the end. The user may choose the color, size/complexity (different parameters for each difficulty) of the maze, and the player (the player can be a shape like a circle or, if you wish, characters). The maze generator parameters need to be imported to the game through a XML file when the it starts. The game menu should contain 2 "links". Play and Scores. When a user selects the Play option, he needs to choose what difficulty he wants to play. Easy, Medium or Difficult. Then he can select the color of the maze and player before starting to play. The actual gameplay is simple. The user has to control the player to the end of the maze in the determined time. 1 minute for Easy, 3 for Medium and 5 for Difficult (assuming that the size of the maze is different. you may choose the lenght of it if you think it is needed). There should be also a "score" text displaying the number of mazes completed in that playthrough. If the user manages to finish the maze within the time, he advances to another maze within the same difficulty, randomly generated. The score is updated. If not, game over, and the game should display a screen with the message "Game Over", the score and a button to save the score to a local file ([login to view URL]) already created on the directory. The user can see the top 5 scores later in the game menu.
