《滾滾卡比》是2000年在Game Boy Color上推出的動作遊戲，在卡比系列裡佔有相當特殊的地位。它是全球第一款在ROM卡帶中內建加速度感測器的作品，因此玩家必須真正「傾斜」手中的掌機才能讓卡比滾動、前進或轉向。更特別的是，只要輕輕向上彈一下整台主機，卡比就會跳起來，這種完全依靠體感操作的設計，在當時沒有 3DS、沒有 Wii、甚至連 DS 都尚未出現的年代，對玩家來說幾乎是一種不可思議的創新體驗。許多人第一次玩到這款遊戲時，都會感覺卡比彷彿真的在掌心裡翻滾，帶來極佳的臨場感與新鮮感。

故事發生在波普之星一如往常的悠閒午後。卡比正在雲朵上安穩午睡，卻被匆匆路過的瓦豆魯迪驚醒。卡比正困惑地眺望時，帝帝帝大王也抱著奇怪的物品急忙經過，並落向噗噗噗之國。卡比心生疑惑，立刻跳上傳送之星追了上去，卻在抵達家鄉後被眼前的景象嚇了一跳——天空竟然一顆星星都沒有了。原來噗噗噗之國的夜空太過美麗，讓帝帝帝大王忍不住嫉妒，於是把天上的星星全部偷走並藏在各個角落。為讓夜空恢復原本的閃耀光芒，卡比踏上尋回星星的旅程。

最核心的玩法，就是利用傾斜GBC主機使卡比在俯視角的路面上滾動。關卡設計有如彈珠台與迷宮的混合體，擺滿窄橋、懸空平台、移動地板與各式陷阱。只要傾斜太大角度，卡比就可能失控滾落平台而損失生命，因此玩家必須以細膩、穩定的方式操控各個方向，才能安全通過障礙。當路上遇到無法跨越的裂縫，只要快速向上甩動主機，卡比就會如彈跳球般跳過缺口。敵人多半不能吸入，碰到就會受傷，因此必須利用跳躍或關卡機關來反擊，例如利用彈簧、風洞或道具像是麥克風來清除威脅。在對抗魔頭時，卡比必須設法以體感操作的方式撞擊弱點，呈現與傳統卡比動作完全不同的戰鬥體驗。

每一個階段都有時間限制，必須在倒數結束前抵達終點，隨著時間逼近零秒，音樂會加快，螢幕會出現急促的催促訊息，形成緊張感十足的氛圍。關卡中散布著能延長時間的道具，也有可前往bonus地區的星星，甚至能蒐集紅星來推動百分百完成度。當玩家通關並收集完所有紅星後，將會解鎖難度更高的困難模式，敵人行動速度變快、平台更危險、操作精度要求更高，整體節奏更加刺激。若能完全破關，標題畫面會變成粉紅色，象徵完美攻略。

除主線關卡之外，還包含五種類型的迷你遊戲，例如射氣球、跳欄比賽、記憶舞蹈、傾斜解謎、以及與雞的瘋狂競速。這些小遊戲都充分運用動作感測的概念，使玩家能以不同方式體驗感應卡匣的魅力。

由於採用特殊卡匣，幾乎只能在Game Boy Color上原生遊玩，即使能在Game Boy Advance上啟動，某些機型會因插卡方向相反而導致感應方向錯亂。GameCube的Game Boy Player也能啟動遊戲，但必須整台主機一起拿起來傾斜，操作既辛苦又可能傷害主機，因此幾乎沒人用這種方式遊玩。2023年透過Nintendo Switch Online，官方模擬原本的體感功能，只需傾斜Joy-Con或整台Switch，就能重現當年的操作手感，讓這款被視為GBC奇作的遊戲第一次真正回到大眾視野。

自推出後，雖然因為特殊操作使得部分玩家覺得不易上手，但在媒體與愛好者間仍獲得相當獨特的評價。它被形容為「被低估的創意精品」，甚至在 2001 年榮獲《Nintendo Power》「最被忽略的遊戲」獎。許多評論者認為，《滾滾卡比》在當年展現任天堂對體感遊戲的超前想法，是Wii、3DS、Switch等體感操作的精神始祖之一。加上可愛的視覺、簡明的音樂與創造性十足的操作方式，使它成為玩家心目中最具實驗色彩的卡比遊戲之一。

Kirby Tilt 'n' Tumble (Japanese title: コロコロカービィ) is the world’s first game cartridge to feature a built-in accelerometer motion sensor, making it a groundbreaking entry in the Kirby series. Released for the Game Boy Color in 2000, the game allows players to control Kirby by physically tilting the console. By tilting the system, Kirby rolls in the corresponding direction, and by flicking it upward, Kirby can jump. The gameplay gives players the sensation of having Kirby roll directly in the palm of their hands. At a time before motion-control consoles such as the Nintendo 3DS, this control scheme was both innovative and novel, providing a fresh way to interact with a platformer. Because of its reliance on the motion-sensitive cartridge, Kirby Tilt 'n' Tumble remained exclusive to the Game Boy Color.

The game’s story is set on the peaceful and idyllic planet Pop Star. Kirby is enjoying a leisurely nap on a cloud when he notices Waddle Dee scurrying by. Soon after, King Dedede rushes past carrying a mysterious object, landing in Dream Land. Suspicious of Dedede’s intentions, Kirby follows him using his Warp Star, only to find that the night sky has been stripped of all its stars. King Dedede, envious of the beauty of the night sky, has stolen the stars and hidden them throughout Dream Land. Determined to restore the sky, Kirby sets off on an adventure to retrieve the stolen stars and return them to their rightful place.

Unlike traditional Kirby games, Kirby does not walk, fly, or inhale enemies in this title. Instead, he rolls like a marble in a top-down environment, where pits and obstacles present constant danger. Players must carefully tilt the Game Boy Color to navigate Kirby safely through the levels, using upward flicks to jump over gaps and interact with stage devices such as bumpers, jump holes, and balloons. The game also incorporates small mini-games that utilize the motion-sensing feature, enhancing its variety and replay value.

The control scheme is highly intuitive yet unique. Tilting the console moves Kirby in the corresponding direction, while flicking it upward makes him bounce. The Nintendo Switch Online version replicates this experience, allowing players to tilt either the Joy-Con controllers or the Switch system itself to control Kirby. This mechanic creates a playful, immersive experience that was widely praised for its novelty and creativity.

The game is structured across eight levels, each containing multiple stages. Each stage has a Red Star that players must collect to achieve 100% completion, as well as optional Blue and Warp Stars that unlock sub-games and bonus content. After finishing all stages and collecting all Red Stars, players can unlock a harder difficulty mode, featuring shorter time limits and tougher enemies, adding challenge for completionists. The sub-games include challenges such as guiding Kirby through obstacle courses, racing, rhythm-based dance sequences, and shooting balloons, all taking advantage of the tilt controls to provide fresh, engaging gameplay.

Enemies range from simple minions to larger bosses like Eyeball, One-Eye Cloud, and ultimately King Dedede. While Kirby cannot inhale or directly attack most enemies in the usual way, players can utilize stage items, temporary invulnerability, and creative interactions with the environment to defeat foes. Boss fights often require launching Kirby into specific weak points to achieve victory, keeping gameplay dynamic and rewarding experimentation.

Kirby Tilt 'n' Tumble is notable for its innovative use of motion controls, charming level design, and engaging sub-games, making it stand out in the Kirby franchise. Despite being overlooked at the time of release, the game was awarded the 2001 Nintendo Power Award for "Most Overlooked Game," and is remembered as a unique and experimental title that showcased Nintendo’s creativity in handheld gaming. The game also marks the final Kirby entry to feature 8-bit graphics and the original English logo, preserving the series’ classic aesthetic before transitioning into later, fully voiced 16-bit and 3D entries.

Overall, Kirby Tilt 'n' Tumble delivers a playful and inventive experience, combining Kirby’s adorable charm with motion-based gameplay that was truly ahead of its time, and it remains a beloved and memorable entry in the series for both its innovation and nostalgic value.
