Puller actually is a game taken from a real concept with natural physics; a well-digger at the bottom of a long well wants to reach well edge who has only one tool, a long rope.
As soon as he climbs the rope and as a natural reaction well wheel on the ground level also starts to spin and releases more ropes, this reaction as well as enemies located on the walls of the well make a very challenging / adventures environment for you as a well-digger through 5 worlds and 50 levels.
