 Program description
 Brief description of the game developed:
 Inspiration taken from Super Mario, Megaman and similar side scroller games.
 SpaceMan character stays stationary while the 'world' moves around him. Objects (coins, meteors and spaceships) enter the screen,
 and move towards '0' on the x-axis. This gives the illusion that the main character is moving.
 
 Objective of the game is to shoot at oncoming enemies, killing (reseting) them while also collecting the Space Dollars and adding to the player score
 -If the SpaceMan collides with the coins, coin is collected, tallied to score and coin is reset
 -If the SpaceMan weapon is fired
 -If the weapon hits a spaceship, kills counter is increased, spaceship is reset 
 -If the SpaceMan collides with spaceship, hitPointLoss is is added, spaceship is reset.
 -If spaceship reaches far left of display, hitPointLoss is is added, spaceship is reset.
 -Once hitPointLoss exceeds maximum maxHitPoints, round is over.
 -Once number of rounds exceeds maximum number of rounds, game is over. Player round statistics are output
