Found a wacky 'game-breaking' bug, try to get a crystal to dust, and then use an acid potion on it. Then try making a card out of that acidified dust. Pretty wacky.
The game is definetely stolen. Check out the profiles of the uploaders, they do not seem to be old enough to do this kind of games at all. Please, respect the original developper and don't claim credit for their game.
