Sorry about that fergie. I foolishly left a bug in there that unless you increase your endurance first, it kills you. Well, I wouldn't say I left it. I couldn't, at the time, figure out how to fix it with all the addition/subtraction/division/multiplication tables behind the scenes. I think I put in the instructions that you have to increase your endurance first but I may be wrong.
Sorry about that! Frustrating to try to play something and die right at the beginning because of the author's idiocy.
