Christmas Cannon Blast

A cannon game that puts angle and power on the same device: moving the mouse up and down tilts the barrel while moving it left and right sets the charge, so a single gesture settles both at once. That is a better idea than it sounds, because it makes aiming continuous instead of a two-step form to fill in. The Christmas dressing is just dressing — underneath it is a clean trajectory puzzle with a wide screen to fire across.
