I like the concept, the handling was just a bit tricky at times for me.
The object of the game is to destroy all the barrels on each level. Destroy the barrels by loading the cannon with that type of number (Prime or Composite) that corresponds to the number of each barrel. Use the mouse to aim and adjust the power of the shot. Left mouse click to fire cannon.
