TODO:
    loading screen for player to join?
    change camera perspective on load.
    add multiplayer functionality / load new player when connected.
    function to create a new player?
    make function to create bullets on the spot and set location to player location
    make objects for background design and platform etc
    collision detection
    implement lives and score mechanics.
    add sound design.
    
    collision detection:
        need to know coords of bullet and player, if at the same spot
        record death
