In the Halloween night, the boy found his home in a basket, in which instead of candy had multiple face and pumpkin. Your task - to help the boy to destroy as many masks, but it needs to be a group of similar individuals. For example, if the bottom is charged in the gun blue mask, then shoot her so that she joined a group of the same blue masks. In case of a group of three masks, they will be removed immediately. To shoot, use the left mouse button.
