Paper Prototyping

Mich and me are being to start paper prototyping .So this means that we basically draw a rough draft of our game on paper.We starteed off ok,but now we've hit a bump in the road.We can't seem to figure out what to put next.We already made our loading page,our main page to begin the game ,character selection page,and rules & objectives page.The problems we are having is to make sure that the paper prototyping and the actual game idea we invisioned is the same.Other then that everything is moving along quite well.
