Another fun physics puzzle type game by Johnny-K (creator of the hand drawn block stacking  Poiser). There are 70 levels with a new style/background every 20 levels.

Goal: Shoot the ragdoll guy from the cannon. Hit the target to go to the next level

The first couple of stages are introductory; things start to get challenging around level 9.

UPDATE: Johnny-K is now offering Ragdoll Cannon with 170 levels and 4 original soundtracks! Check it out here!
