One of the absolute best games for the Game Boy. The depth of Kirby and his friends' movesets is incredible for the DMG. The Super Game Boy effects are really impressive, in how it's able to use careful palette swapping and positioning of assets to convey more colour than would otherwise be possible. You even get little extra PCM samples on the title screen. This is HAL showing off their mastery of the Game Boy as a platform.
