《忍者茶茶丸：銀河大作戰》由 Jaleco 於 1991 年 3 月 29 日在任天堂 Famicom 推出，是《忍者茶茶丸》系列在紅白機上的最後一作，也是一部風格轉變最為劇烈的作品。與系列前作相比，完全跳脫定格畫面（一代）或 RPG 忍法帖的風格，徹底進化為高速橫向捲軸動作遊戲，並將舞台從古日本搬到遙遠的外太空。

在紅白機末期，Jaleco 展現極高的畫面技術，使這款遊戲充滿 16 位元主機的質感。角色茶茶丸不再是傳統忍者，而是穿上太空裝甲的戰士，場景跨越各個行星、太空船與未來都市，色彩鮮豔且細節豐富。遊戲引入類似《音速小子》和《超級瑪利歐》的高速奔跑與斜坡滑行系統，讓玩家感受到極高的速度感。遊戲亦支援雙人合作模式，1P 操作茶茶丸，2P 操作女主角櫻花公主，兩人的性能略有差異，櫻花公主的動作更輕盈靈活。

劇情上，大幅跳脫傳統民間傳說框架。邪惡黑暗軍團侵略銀河系各行星，茶茶丸與櫻花公主為守護宇宙和平，穿上黑科技研發的「強化忍服」，搭乘太空船出征。必須闖過八個充滿外星生物與機器兵團的行星關卡，最終擊敗黑暗皇帝，拯救宇宙。

核心操作方面，機制多元且注重速度與物理慣性。踩踏敵人使其暫時昏迷，按住方向鍵衝刺後在斜坡上滑行甚至發動滑行攻擊，關卡中還可取得各種強化道具如擴散彈或威力強大的手榴彈，讓原本近戰的忍者具備遠程火力。遊戲亮點之一是多樣化載具，茶茶丸能駕駛太空坦克、飛行滑板，甚至是機器龍進行特殊關卡，極大增加遊戲的新鮮感。

在市場上獲得「手感一流、創意十足」的高度評價。評論家認為本作吸收當時知名動作遊戲的優點，保留茶茶丸系列的可愛風格，是紅白機末期完成度極高的作品。雖然部分老玩家對從古風轉向科幻的風格感到意外，但紮實的關卡設計很快贏得好評。歷史上，它被視為茶茶丸系列在 8 位元時代最完美的謝幕之作，由於發售時正值 SFC 初期，許多玩家錯過這款傑作，使其成為收藏市場上的珍品。

這款遊戲最經典的回憶，莫過於「看著小忍者茶茶丸穿著厚重的太空衣，卻能像風一樣在銀河系的斜坡上奔馳」。還記得當年為了在最後的要塞關卡保命，死命守著那台太空坦克的瞬間嗎？

Ninja Jajamaru: Galactic Great Battle was released by Jaleco on March 29, 1991, for the Nintendo Famicom. It stands as the final installment of the Ninja Jajamaru series on the Famicom and represents the most dramatic stylistic shift in the franchise. Unlike its predecessors, which featured freeze-frame action (the first game) or RPG-style gameplay (Ninpōchō), this entry fully evolved into a high-speed side-scrolling action game, relocating the setting from feudal Japan to the far reaches of outer space.

Released at the tail end of the Famicom era, Jaleco showcased impressive graphical capabilities, giving the game a quality comparable to 16-bit consoles. Jajamaru is no longer a traditional ninja but dons a space armor suit, traversing planets, spacecraft, and futuristic cities. The visuals are vibrant and detailed, while the game introduces high-speed running and slope-sliding mechanics reminiscent of Sonic the Hedgehog and Super Mario, delivering an exhilarating sense of momentum. The game also supports two-player cooperative play, with Player 1 controlling Jajamaru and Player 2 taking on Princess Sakura, who is more agile and nimble.

The story breaks away from traditional folklore. An evil Dark Army invades planets across the galaxy, and to protect cosmic peace, Jajamaru and Princess Sakura don technologically enhanced “Ninja Suits” and set out in a spaceship. Players must navigate eight stages filled with alien creatures and mechanized soldiers, ultimately confronting the Dark Emperor to save the galaxy.

Gameplay mechanics are diverse, emphasizing speed and inertia. Jajamaru can stomp enemies to temporarily stun them, dash and slide down slopes, and execute sliding attacks. Various power-ups, such as spread shots and high-powered grenades, give the originally melee-focused ninja strong ranged capabilities. A standout feature is the inclusion of vehicles: Jajamaru can pilot space tanks, hoverboards, and even mechanized dragons for special stages, significantly enhancing gameplay variety.

Galactic Great Battle received high praise for its precise controls and creativity. Critics highlighted its ability to incorporate contemporary action game elements while maintaining the series’ signature charm, making it one of the highest-quality Famicom titles at the end of the system’s life. Although longtime fans were initially surprised by the shift from traditional Japanese themes to sci-fi, the solid level design quickly won approval. Historically, it is regarded as the perfect farewell to the Jajamaru series on 8-bit consoles, and due to its release during the early Super Famicom era, many players missed it, making it a cherished collector’s item today.

The most memorable moments of the game remain watching little ninja Jajamaru, clad in heavy space armor, dash like the wind across galactic slopes. Do you remember the tense thrill of clinging to the space tank to survive the final fortress stage?
