Hello

I was playing "bait and switch" on armor games ("Sorry you can't post url yet", stupid forum!) and I was stuck at one level and the game doesn't allow to grind money to upgrade the weapons, so I though I could help me a little bit with CE. So I tried to find out the address of the money in 2 bytes, 4 bytes, float, double but nothing, I tried to start with a unknown initial values and find it out with increased and decreased values, but nothing.
So I was little clue less, I don't care for the game any more, but I would like to know, how they have done to hide the value and what do you have to do to find it?
