Testing the speeds of the monsters and the scrolling background.
The monsters are quite choppy when they move at higher speeds. I need to
find a way to resolve this.
Changed the clock to now increment as the player stays alive, although
there is no real way to end the game yet.
Will be implementing coins that add more points, but may put the
character in danger if they get too greedy.
Will also be adding some lives to the main player to keep it a little
more fair.
