Kirby Tilt 'n' Tumble is an action puzzle video game developed by HAL Laboratory and published by Nintendo for the Game Boy Color handheld video game console. It was released in Japan on August 23, 2000 and in North America on April 11, 2001. Due to the cartridge having a built-in accelerometer, it has a unique shape, as well as a unique transparent pink color in reference to Kirby. The game will be released as part of the Nintendo Switch Online service in 2023. Plot The game begins with Kirby napping on a cloud, when he is awakened as a Waddle Dee walks by, carrying a round pinball-like bumper. He then sees King Dedede, carrying a long bumper. Suspicious of the King's intentions, Kirby hops on a warp star and follows him, determined to find out what he is up to. Soon, Kirby discovers that Dream Land has lost its stars and sets off to get them back. Gameplay Kirby Tilt 'n' Tumble uses a series of accelerometers to control Kirby. The goal of the game is to guide Kirby to the level's goal within the allotted time by tilting the Game Boy in the direction in which the player wishes to move him. The game registers a "pop" action when the player quickly jerks the Game Boy, rotating the game toward the user (as if flipping a pancake); doing so will fling Kirby into the air. The game revolves around the collection of the numerous stars strewn about the levels. To beat the game entirely, the player must collect each level's red star. This will unlock the bonus worlds, where they are slightly harder versions, and players start with less time. The timer counts down until the player has reached the level's end. The player can increase the timer by rolling Kirby over clock tiles, stopping the roulette on the timer, picking up clocks that add ten seconds, or by passing checkpoints. When the timer drops below 50 seconds, an alarm sounds, warning the player to hurry up and finish the level, and the music that was previously playing changes to a more fast-paced version. If the time limit reaches zero, Kirby will lose a life. Development Kirby Tilt 'n' Tumble started development in April 1999. It was originally titled Koro Monkey (Monkey Tilt 'N Tumble) and starred a monkey. After discussing with Shigeru Miyamoto, the developers then switched
