Updates to Scratch have made this laggy, so after clicking the flag twice, go into options, click visuals and activate pen mode and it will run much smoother. Controls: Movement: WASD or Arrows Shooting: Mouse Click Melee: E or V Switch Weapons: Scroll or Keys 1 and 2 Pause: Space More info in-game.
