If you die in this game you've lost everything and have to restart from the last time you used wings or saved the game. So don't go and do 50 levels in a row, then die on an enemy because you forgot to use a potion or you'll end up like me: at level 1 with nothing.
Is there any place in the game that actually explains what each element icon is supposed to represent? I see one that looks like a smashed brain, one is obviously fire, another one looks like a smelly turd pile...
 "The Enchanted Cave"){kind=icon}
 "Protector IV"){kind=icon}
