It's an addictive game, which I have played so many times again and again. The addition of The Advanced Edition free DLC helped improve the game to have more of a progession feel to it...as if each run is not in vain. Plus it brought in a new level of play. I also like the fact that you can disable it if you feel you what to play the original verson of the game (this is one of few games I know that do that).

Each game is different as it is a roguelike, so at times it feels like you are breezing though and then you mess up somewhere and you have to scramble to fix it...you might just save one person and escape that fight and go on to do really well or you may just die because a computer virus disables one or more of the important things you need to win, or you may by mistake miss something (like you opened all the doors and there is no oxgen)....so many things could happen.

Good luck in you journeys.
