You are an officer who has the sole goal in life to direct traffic. There are no traffic lights at the intersection you have been assigned. The only thing keeping cars from crashing is you. Simply click cars once to stop them, and click stopped cars to accelerate them. Every car that makes it successfully across will earn you $10. Money can be spent at the shop by pressing "S" on items like the Oil Slick, Land Mine, Teleporter, and Barricade. After purchasing an item, the demand for it skyrockets so the price increases by $1. There are three upgrades for each item as well. If you allow three crashes to occur, HQ will promptly fire you but you will be able to submit your number of total cars.
