《閃亮星星之夜》（Kira Kira Star Night!）是漫畫家與插畫家RIKI於2013年推出的橫向捲軸動作遊戲。最初是以「向紅白機（FC）30 週年致敬」為概念發想，因此無論在圖像、音樂、節奏甚至程式架構，都忠實地以紅白機的硬體限制為基準打造。以CD-ROM形式發售，內含可於模擬器運行的NES檔案，同時也推出能在真正的紅白機與相容機上運作的非授權卡匣版。而後陸續推出《Kira Kira Star Night DX》、《Kira Kira Star Night ふるさと納税版》、《Kira Kira Star Night exa》等版本，皆為原作延伸與改良的變體。

RIKI原本只是熱衷於收藏懷舊遊戲的玩家，卻因興趣而踏上自製遊戲的道路。他邀請曾在1980年代擔任專業程式師的開發者協助以組合語言完成紅白機規格的程式內容，並在持續繪畫工作的情況下花費一年七個月才完成遊戲。為給玩家帶來驚喜，他在遊戲完成前一直將製作進度保密，直到2013年7月15日，也就是紅白機問世滿三十年的日子，才以一段宣傳影片正式公開本作。

故事有著童話般的輕盈氣質。某天，主角「キララ」（Kirara）的房間裡突然闖入一隻會說話的小老鼠，而這隻老鼠其實是她的男友「ナイト」（Knight）。Knight 為了取得象徵願望成真的「一番星」，偷偷潛入星之城堡，卻意外把沉睡的星星們弄得四散逃逸。月之女神見他闖下大禍，便將他變成老鼠，並命令他只有在讓夜空重新恢復光輝後才能變回人類。Knight 深知自己無法獨力完成，於是懇求 Kirara 幫助他。為了拯救戀人，Kirara 換上魔法鞋，從窗戶一躍而出，展開收集群星的奇幻冒險。

遊戲的操作簡單直觀，卻節奏明快並充滿爽快感。玩家可選擇兩種難度（Level 1 或 Level 2），每種難度都包含九個關卡。畫面會自動橫向捲動，必須在有限時間內達成關卡規定的星星收集數目。星星會以不同軌跡在空中飛舞，有些成群出現，有些高速掠過，玩家必須運用左右移動與大小跳躍技巧，抓準時機取得星星。時間一到，只要收集數量達標就能進入下一關，不足便會失敗。看似簡單的規則透過速度與判斷的交替，形成意外耐玩的節奏感。

本作的魅力不僅在玩法本身，也在於它在紅白機規格內展現出的視覺張力。背景與角色皆以像素精美呈現，並搭配細膩且極具風格的 8-bit 音樂，讓整體體驗宛如真正的 1980 年代新品。由於採用實機可執行的卡匣形式發售，它不僅是懷舊風作品，更是一款能跨越世代、以現代美學重塑古典感的「新時代紅白機遊戲」。

遊戲推出後獲得懷舊玩家、大型展會與紅白機愛好者的高度關注。許多人驚訝於它不是改版、不是移植，而是一款真正以現代技術重新開發、卻完全遵守 8-bit 架構限制的原創作品。尤其 DX 版與其後的加強版本加入更多音樂人協力創作，使遊戲的可聽性、可玩性皆大幅提升。雖然它不是商業主流大作，但在復古遊戲圈中受到極高評價，也被視為少數能在21世紀仍忠實呈現「紅白機精神」的代表作之一。

《閃亮星星之夜》之所以令人印象深刻，是因為它既是一封寫給紅白機的情書，也是由熱愛驅動的創作奇蹟。遊戲本身簡潔純粹、沒有複雜數值與繁瑣系統，但用音樂、節奏與視覺語彙刻畫出一段輕快又浪漫的星之旅程。對熱愛8-bit美學、動作遊戲與懷舊文化的人而言，它是值得親手體驗的珍貴作品。

Kira Kira Star Night! is a side-scrolling action game released in 2013 by manga artist and illustrator RIKI. The project began as a tribute to the 30th anniversary of the Famicom (NES), and every aspect—from graphics and music to pacing and even programming structure—was built strictly within the hardware limitations of the original 8-bit console. The game was distributed on CD-ROM containing an NES file compatible with emulators, and also as an unlicensed physical cartridge that runs on real Famicom hardware and clone systems. Several enhanced versions were later released, such as Kira Kira Star Night DX, Kira Kira Star Night Furusato Tax Edition, and Kira Kira Star Night exa, all of which further expanded or refined the original project.

RIKI originally entered the project simply as a passionate collector of retro games. His interest eventually led him to create his own game, involving a professional programmer from the 1980s familiar with assembly-language development for the Famicom. While continuing his illustration work, RIKI spent a year and seven months completing the game. To surprise fans, he kept the project entirely secret until July 15, 2013—exactly thirty years after the Famicom’s launch—when he finally revealed the game through an official promotional video.

The story of Kira Kira Star Night! carries a charming, fairy-tale tone. One night, a talking mouse bursts into the room of the heroine, Kirara—but the mouse is actually her boyfriend, Knight, transformed by the Moon Goddess. In an attempt to steal the “First Star,” which grants wishes, Knight sneaked into the Star Castle and accidentally scattered the sleeping stars across the night sky. As punishment, the goddess turned him into a mouse, and he cannot return to human form until the stars are restored. Knowing he cannot complete the task alone, he pleads with Kirara to help him. Determined to save him, Kirara puts on her magical shoes, leaps out the window, and sets off on a fantastical journey to gather the lost stars.

Gameplay is simple and intuitive, yet fast-paced and satisfying. Players choose between two difficulty levels (Level 1 or Level 2), each consisting of nine stages. The screen auto-scrolls horizontally, and Kirara must collect a minimum number of stars within a time limit. Stars move in different patterns—appearing in clusters, sweeping across the screen, or following curved paths. Players use left-right movement and small or large jumps to gather as many stars as possible. When time runs out, clearing the stage depends on whether the required number of stars has been collected. Although easy to understand, the combination of timing, movement, and rhythm makes the game surprisingly engaging.

A major part of the game’s charm lies in its ability to express striking visual and audio style within true Famicom limits. Both backgrounds and character sprites are beautifully crafted pixel art, complemented by stylish and finely tuned 8-bit chiptune music. Because the game was released as an actual functioning Famicom cartridge, it stands not only as a nostalgic homage but also as a modern reinterpretation of classic 8-bit aesthetics—essentially a new Famicom game made decades after the console’s heyday.

Upon release, the game drew considerable attention from retro enthusiasts, collectors, and fans at major gaming events. Many were astonished that it was not a hack, port, or demake, but a fully original title developed completely within 8-bit technical restrictions. The DX edition and later enhanced versions included contributions from various chiptune musicians, significantly enriching the soundtrack and overall experience. Though not a mainstream commercial title, it is widely praised within the retro-gaming community and is often cited as one of the most authentic modern expressions of “true Famicom spirit.”

Ultimately, Kira Kira Star Night! leaves a strong impression because it is both a love letter to the Famicom and a testament to how passion can produce creative miracles. The game is simple and pure—free of complicated systems or heavy mechanics—yet conveys a bright, rhythmic, and romantic journey through stars using visuals, music, and movement alone. For fans of 8-bit aesthetics, action games, or retro culture, it stands as a rare and memorable gem well worth experiencing firsthand.
