Okay. FIRST- Get a second player. It can be anyone, as long as they know how to operate a computer mouse and keyboard and are reasonably competent. SECOND- Choose one player to be the Clicker, and one to be the Hider. The Hider uses the arrow keys, and the Clicker uses the mouse or trackpad. THIRD- Start the game. If you have been using Scratch for any amount of time you know how to do this. FOURTH- When the game starts, the Hider and 20 identical clones will be spread around the screen. The Hider must try to blend in with the crowd as the Clicker tries to click the Hider without accidentally clicking anyone else. FIFTH- Maybe Favourite or Comment or something? gah my fingers hurt
