DEADLine

You wake up into the world having just recently been created by a wizard. He tells you that your purpose is to search the ever-shuffling dungeon to find the prize at the end, the Golden Heart. The Golden Heart is the key to perfecting the clones the wizard makes, and until then, you and the clones after you will only ever live for a limited time. 

You must brave each floor fighting enemies and searching for resources to buy you just a little more time until… your deadline.
