Golvellius: Valley of Doom Cheats

If you have all the hearts for your meter, and both the green and purple herbs, fill to full life, then get dropped to nothing. Let all the herbs get used automaticcaly like normal, but when your last hit is taken off, you won't die. You'll be invincible until you heal, so don't pick up any of those potions that enemies drop.

Yet another use of the up-left-1-2 button combo. Hold those buttons down while watching the opening sequence. When the old woman gives you the sword, she'll instead be a sound test.
