I like the idea, but I don't think you thought out the rules well. You first start getting score after first shot, but stop getting score when you fail to get someone under your control. Then it starts again when you fill (almost fill?) the reputation bar? So the winning strategy is to do nothing at all.
Shouldn't the probability of getting someone under your control depend on your score instead of the reputation? Or maybe it would make more sense if those two were one thing? Randomness doesn't feel right (I had 3 or 4 consequent fails on a guy with 20 rep) and the map is pretty empty.
I like the shader you've used :)
