Third version of Roly-Poly, where you just have to shoot the evil ones, but ont the good ones! You have to kill all the evil ones, but not the good ones, to pass to the next level. With a comprehensive level editor that allows you to create your own levels.
Move the mouse to aim; the distance from the mouse pointer to the cannon defines the power of the shot (if the mouse pointer is away, the shot will be stronger); click to shoot. When you finish a level, a tinkling poster will allow you to pass to the next level. In the level editor, use mouse clicks to interact.
