The story of Bedlam is one of survival as a lone cannon in a world filled with enemy ships. The game takes place on a star-shaped geometric form that changes shape and size as the player progresses through levels, adding an extra layer of challenge to each stage.
The gameplay of Bedlam involves controlling a rotating cannon at the center of the screen, aiming to destroy enemy ships that spawn from the changing star shape. Each ship has its own unique attack pattern, requiring players to adapt and react quickly to survive. The player can also use special moves like a quick turn or the "zap" button to take down multiple enemies at once.
