Sakurai left HAL on August 5, 2003, after growing tired of the sequelization passively forced by HAL, ending his work on the Kirby series. "It was tough for me to see that every time I made a new game, people automatically assumed that a sequel was coming," Sakurai commented, in an interview with Nintendo Dream, two weeks after he resigned from HAL. He explained that, "even if it's a sequel, lots of people have to give their all to make a game, but some people think the sequel process happens naturally".
