Adventurers Just Want to Rest in Fancy Graves

From BoardGameGeek:

You are adventurers. Explore the dungeon and earn as many coins as you can. Even if you lose your life, don't worry. Your bravery will be honored with a fancy grave. But remember, the finest graves go to those who claim them first... Will you survive and rake in riches, or be the first to fall in glory? Even death is a strategy! Make your mark! In a game of Adventurers Just Want to Rest in Fancy Graves, each round you draw three Dungeon Cards from the top or bottom of the Draw Pile (Dungeon), play one, and return the rest. Dungeon Cards come in three flavors: monsters (deal damage, grant points), treasures (grant a few points, no damage), and potions (heal damage). If damage taken exceeds 5, you're knocked out, forfeiting all collected points. But you pick a Grave Card from a face-up row: best graves go first, so being knocked out early nets the richest pick, and being knocked out last means scraping the leftovers. Alternatively, at any point you may retreat (leave the dungeon), banking all points collected so far. When all players have either retreated or been knocked out, the round ends. After three rounds, the player with the highest score is the winner. Will you race to get knocked out early and claim the best grave, or bet on staying alive long enough to out-collect everyone else through monsters and treasure, knowing the longer you wait, the worse your grave options get?
