Ghosts 'n Goblins Cheats

Do the frog trick and time your 15th hit so that the frog spell hits you as the time runs out but before the death animation stops. The 0 in the minutes space of the timer will then change indefinitely in a fixed sequence every minute to a different number, letter, symbol, blank, or garbage character, sometimes in a different font. Arthur/frog (revived) will be either normal or disfigured and the music will stop. The glitch will last until Arthur dies or completes the level.

Duck and then shoot a tombstone 15 times in a row and an angel character will appear. This angel will fire a bolt at you. Let it hit you and you'll become a frog.
