An artillery game reduced to two decisions: where to point and how hard to fire. You aim with the mouse, then hold the button to build power and release at the level you want. There is no wind, no obstacle to arc over on the first levels and nothing to manage between shots, so the whole game is learning how power maps to distance. Cannon Plunder is best read as a calibration puzzle — once the mapping is in your hands, the levels become a formality.
