The story behind the game is that once upon a time King Triangulos ruled the kingdom of Bentangle. The king loved blocks, he'd played with them since he was a child and he loved them almost as much as he loved his daughter, the beautiful Princess Pentaguin. The princess must marry someone worthy so the king had a series of rooms constructed such that extreme cleverness in moving and using blocks was necessary to escape from each. The suitor who could complete all these puzzles would be a fit match for his daughter. Block-man is a commoner in the land of Bentangle but he loved the princess nonetheless and vowed to win her hand in marriage.
