• This code may mess the game, it messes the graphics, and the dude at the beginning says something about AOL, and when you attack an enemy, you throw them into outerspace, after you do that and you hit attack again and you fly into outerspace and restart.
• Should affect most of the enemies in the game. This seems to make the first boss impossible to beat so make sure you turn this off before you get to it.
