The lights are on
Beat the final boss and press A as the credits roll. The music will change and a minigame will start. The object of this game is to collect the yellow letters that spell "THANK YOU FOR PLAYING." Beat this to unlock the Ultimate All-Shooters Minigame.
Note: During the sequence in the credits while you try to get the letters spelling "THANK YOU FOR PLAYING" there is an easy way to do it: fall in the pits. By doing so you can then reappear in the sky and, with good timing, simply fall right on the letter. One thing to note is that the letters are for enough apart so that falling in the pit directly after getting a letter will not result in missing the next letter that appears.
Beat the game with a character to unlock his or her character in the minigame.
