Cyber City is a harsh and competitive place. Run and jump across the roofs of the skyscrapers and try to collect the wads of cash. One way to collect cash is to beat up the other stickmen that cross your path. The stickmen will also pick fights with each other. You can choose to hover at the periphery of each fight and swoop in once a beaten stickman drops any money. Make sure you don't fall over the edge of the roof though! You won't survive the fall.
