    Once the game starts a random letter from A-Z will be displayed on the screen.
    If it is a consonant then you press the right button.
    If it is a vowel then you press the left button.
    You must press the corresponding button within the time period for the current level.

    The initial allowed time is defined as INITIAL_LIMIT.
    The amount by which the time allowed decreases at each level is defined by SPEEDUP.
    The point at which a level up occurs is defined as LEVEL_UP.
+   These can all be tweaked by updating the #defines.
