One of my favourite things about this game and indeed all of Darktoz's games is he puts a happy (If that's what you want) ending in the game you can work for and escape. It's a nice little addition and feels rewarding after all the hardships the player character goes through.
Yes, well, I don't think many players chose the escape ending. The way your "friends" slaves treat you, you're as much a slave to the black efles as you are to your own fellow prisoners, you have to serve them everything on a silver platter and suffer the slightest whim, if you refuse, they complain.
