It's great fun to play Slap & Run, a game that consists entirely of fast slaps and dashes. Make yourself the city's most notorious parasite, and then make sure everyone knows about it. You go about town, giving everyone you come across a good, hard slap. Repeatedly crossing the middle of the running lane will increase your chances of slapping other players.
As you continue to get smacked, more and more people will come after you. Click the screen to hop over obstacles when they emerge. If you start slapping random people in the crowd, they will start trying to catch you. You're running from an angry mob. Therefore, you have to avoid their arrows and obstacles. Do something right now!
Just swipe left and right to move your character.
