/**
 * Project Title: Platformer Game in C
 * Creator: Tyler Loeper, for CS50 Miami, Summer 2016 cohort.
 * Completed: 9/3/2016
 * 
 * Overview:
 * This is a small game in c I created to mimic the 1990s mario games. In it a small 2d world is rendered, and the player (graphically represented by the letter "t") is tasked 
 * with reaching the of the world and win by touching a flag "p". The player has several moves availible, including dashes and jumps, and must avoid spikes and falls in order to reach the end. 
 * 
 * The game makes use of several function prototypes, and uses pointers to track the position of the player. Pointers were necessary because these variables (worldpositionx, and worldpositiony) needed to be 
 * changed globally, and not locally, in order for the functions that tracked position to work together. I tried using local variables originally, but the tracking didnt work. 
 * Hence the current use of pointers.
 * 
 * For your reference, here is a list showing what each number in the array of arrays (2d game world) represents.
        0 = air
        1 = solid (ground)
        2 = player
        3 = kill condition
        4 = win condition
        5 = flag
        6 = flag mast
        7 = flag ground
        8 = animation
 * Each number is in the array of arrays, but is represented differently graphically in terminal by using printf (if number is present). For example all 0s print as " ", and the player "2" prints as "t".
 * 
 * I hope you enjoy the game!
 * 
 * Hints for playing the game:
 * Feel free to use dashes instead of regular movement to get around the big chunks of empty space faster. 
 * If you fall into the hole, get out by using jump.
