There are 50 levels of the dungeon, and you have to make your way in one playthrough. If you die, you start over. The only factor connecting you to your last player is a gravestone at the level you died on with your name on it and one item that was in your inventory that you can take. Completing all 50 levels with one life probably took me between 3 and 4 hours, not that long, but just imagine being 3 hours in and dying on the 45th level... It can be devestating
And yet, I keep playing. I feel compelled to start right back up again with a new character. Maybe I choose a different class this time. Maybe I change my strategy by utilizing different skills. Every time you make it past the level you died at before gives a great feeling of success and progress. Permanent death also brings a nostalgic feeling. Remember when arcades didn't have continues? While this aspect of the game can be frustrating for some, it really adds a whole new dynamic to the game, and makes you play differently. Combine that with the fast paced battles, plenty of loot, and random levels makes this game my favorite Xbox Live Indie game thus far!
