This is an early prototype for a deckbuilder in the same vain as Dominion or Legendary Encounters, with a dungeon crawling theme.

If you've played a deckbuilder before it should be pretty quick to pick up, if not:

Every turn, you use actions to play action cards (all the ones that aren't explore cards). Playing cards can get you more actions (so you can play another card) or draw more cards, as well as do things like attack enemies or even remove cards from your deck entirely
