game mechenics update

By March 5, we were able to establish several milestones regarding the game mechanics

• We created an actual player level where all the art asset, model and animation has been incorporated instead of using simple geometric shapes. 
• added a timer and round system to indicate each round and it gets harder as the round increases
• added main and character selection menu where players can choose how many are playing
• added enemies that chase after the closest player
• added soundtracks and sound effects to the game
• made sure players die when they fell out of the map
