I can't remember the last time I was this disappointed in a game. I feel like I really have no control on the game play. At best I get a random string of good luck. At worst, it's a series of bad choices lined up behind each other. And the Life Span bar is terrible. Health or Life Span, not both.
I enjoyed the game on the lower levels, but was more than annoyed with the "harder" and "nightmare" modes. Just felt as if whatever percentage was shown was not indicative of the REAL percentage of danger.
