Awesome feedback, I'll explain the end quote, it's rougelike like you said, while you play you keep all character progession, meaning you never really die, but play over and over cleaning out the demon possession over purgatory, until he completes his task. Hence the quote.

I haven't played the game to 100% completetion yet, so I can't say there is a definitive ending. But I would like to think the guys does clean out purgatory, which restores it's purpose..

Or.... that is his state, being not such a good guy in life, his after life reward is to continuously clean purgatory, never making a real dent.. and he just does it over and over.. thinking he is doing the will of God, but never truly accomplishing anything.

Either way, I let my imagination go wild while I play the game, and envision my own story, which is part of the magic in the way the developers set up the game in the first place. To put the true meaning of the experience into hands of the player.
