"Kirby's Block Ball" is a 1995 action video game, a spin-off from the "Kirby" series for the Game Boy portable console. It is a "Breakout" clone; the player controls paddles along the screen's edge to knock a bouncing ball, Kirby, into destructible bricks. The game's 55 levels include power-ups, bonus rounds, and minigames. "Kirby's Block Ball" was developed by HAL Laboratory and Nintendo R&D1. The team spent half a year revising the gameplay to match Kirby's signature characteristics. "Kirby's Block Ball" was published by Nintendo first in Japan in 1995, later in Europe, and last in North America in 1996.
