I really like the idea, it reminds me of the a psychology study/idea I encountered over the years. I like this however so much better because it puts people in real time in the driver seat. I think the only thing, that you might want to add after the jam is a CPU element so that if you are playing alone on the game it is still entertaining. Of course you might have already been too smart and added that and I just never noticed :) Either way I really love this game.
