Solo Crawling

From BoardGameGeek:

Solo Crawling is a customizable single-player dungeon-crawling card game built around rogue-like mechanics and unpredictable encounters. It's played utilizing multiple decks to randomize everything from dungeon layout, encounters, loot, and gear as you crawl through the dungeon to battle a randomized boss. A key feature is the ability to tailor each deck to customize your experience. You can increase or decrease the amount of dungeon cards to adjust the maximum size of the dungeon, adjust the amount of loot, gear, healing potions, and more to make the experience easier or harder. With future expansions in the works, you will be able to further customize the experience, adding multiple levels to the dungeon. -description from the publisher
