A Nightmare on Sesame Street Cheats

Level Skip:
-----------
Each level is brought to you by the letter A, E, I, O, or U. At the title 
screen, press A for level 1, E for level 2, I for level 3, O for level 4, 
and U for level 5. 


Secret Level:
------------- 
Don't forget, the letter Y is sometimes a vowel. At the title screen, press 
Y for a secret level dedicated to BieberSoft's WonderDweeb. 


Second Weapon:
--------------
This is more of a glitch than a cheat. When playing a one player game with 
a joystick, press player 2's button #2 (Ctrl is the default) and a second 
stationary weapon will appear in the middle of the screen. To cycle through
the weapons, press player 2's button #2. 


Control Both Characters:
------------------------
Also a glitch. At the start screen, press Ctrl-Y and set the controls for 
both players the same (i.e. have both of them use Joystick 1) then start a
two player game. You can now control both Ernie and Bert with one joystick/
keyboard
