We would be very happy if you post something about your games/apps (made with Cerberus X or Monkey X) here in this section. One or more screenshots in your first post would be awesome and definitely show off your creation even better!
I had touch screen in mind with controlling the worm. With mouse, the pointer can be anywhere in the canvas area, when left mouse button is pressed down the direction is the main direction the mouse was moved. Quite hard at first with the mouse, I admit it. The game is quite tolerant as it comes to the worm crossing itself.
