赤ナマコは食べられる 青ナマコも食べられる 黄ナマコは分裂する 紫ナマコは突然変異 白ナマコも突然変異
ゲーム内容はピクミン4のダンドリバトルにかなり近い。マルチタスクが重要なので複数の作業を同時に管理するのが好きなら楽しめると思う。 操作性は割と難がある。UIが全体的に小さく高低差が慣れるまで分かりづらいので、起爆スイッチを踏んだ後に床をクリックして移動したつもりが、壁上を誤クリックして立ち止まったままナマコちゃんが大量に爆死した時は悲しくなった。 一部の壁やエリアは炎、氷、岩タイプ等複数の属性があり、それぞれ同じタイプのナマコで対応するんだけど、手待ちが発生してる時以外は属性毎に纏めて切り替えが出来ず、ゴマ粒みたいなサイズの中から手作業で引き抜かないといけないのでかなりしんどい。 この仕様の厳しさは最終ステージが特に顕著。一定間隔でランダムなエリアに即死攻撃を放ってくるので、複数のナマコの場所を常に管理しながら、適宜手動で属性に合った場所に配置を変えないといけない為、難易度が異常に高い。
ナマコに除染作業をさせるRTSゲーム。時々パズルっぽい部分もあります。 RTSは長いイメージがありましたが、1ステージ5~10分程度のものが多く遊びやすいです。 ゴールドランクを取ろうとすると、かなりの試行錯誤が必要になるため、一つのステージを何度も遊ぶことになりますがその試行錯誤の過程がとても楽しいです。 可愛らしい見た目を楽しむ時間は全くありませんが、1ステージの思考錯誤を短時間で何度も何度も繰り返せる楽しさがあります。
トウキョウマップ以外はクリアしたので。 面白い。ピクミンから戦闘を抜いて見下ろし視点にしたゲームとして成立している。 難易度も高めで最適化が楽しい。 しかし色々と言いたい点も出てくるところでもある。 まず操作量が多い。マルチプレイ前提だからかソロでやっているとどうしても手が回らない。 マウス操作だと仕方ないのかもしれないが複数種のナマコを一緒に動かしたが最後分離がメンドクサイ。 まあそれはどうにかなるんだが、、、 一部マップが広すぎる。 中盤に入るころから感じるところだが、マップが広すぎるうえに複雑すぎる。 仕事をしていないナマコがいてもマップが広すぎてどこにいるのかわからないことがある。 この類のゲームにおいてマップが広く高難度であることはデメリットが大きいと教えてくれた。 トウキョウマップは最後の謎解きが解けずに失敗。戻るまで10分以上かかるのでめんどくさくなって終了。 程よいサイズのマップがもう少し欲しいところ。
楽しい! おっとりとしたナマコを眺める景観重視なゲームかと思いきや、作業効率を考えてオブジェクトに移動する順番、ナマコの数、追加するナマコの数の最適化をしようと思うとさながら現場監督のようなマルチタスクが求められる忙しさ。どれだけやってもタイムが伸びないステージもあれば、閃きや計算で早くなるステージもあって中毒性がとても高いです。
NAMAKORIUM, developed and published by Polyscape Inc., is a cooperative real-time strategy game that takes an unusual concept and transforms it into an engaging management experience built around teamwork, environmental recovery, and fast decision-making. Instead of commanding armies or expanding empires through conquest, players take responsibility for restoring damaged oceans using specialized sea cucumber workers called Namako. The result is a strategy game that feels refreshingly different from genre traditions while maintaining enough mechanical depth to reward planning and coordination. The central objective revolves around cleaning polluted marine environments before limited resources disappear entirely. While the concept initially sounds lighthearted, NAMAKORIUM quickly reveals meaningful strategy systems hidden beneath its charming presentation. Players are constantly balancing priorities, assigning jobs, gathering resources, constructing important facilities, and responding to changing conditions that threaten long-term success. Every decision matters because inefficiency can quickly create problems that spread across an entire operation. What makes the experience particularly engaging is how strongly it emphasizes cooperation. Designed primarily around multiplayer teamwork, the game supports groups working together to restore damaged ecosystems under growing pressure. Communication becomes one of the most important tools available. Players naturally divide responsibilities, coordinate movement, and adjust strategies whenever unexpected situations appear. Even carefully planned operations can collapse into frantic improvisation when new problems emerge, creating memorable moments that highlight the unpredictable appeal of cooperative games. The Namako themselves introduce surprising tactical depth. Different sea cucumbers specialize in different responsibilities, encouraging players to think carefully about assignments rather than treating workers as interchangeable units. Certain Namako perform resource collection efficiently while others excel at mining operations or navigating environmental hazards. Some specialize in surviving extreme conditions while others contribute support functions necessary for maintaining larger restoration efforts. Success depends heavily on understanding these strengths and building effective systems around them. Resource management serves as the foundation supporting everything else. Gathering materials, expanding operations, and maintaining productivity all require careful planning. Unlike slower management games that allow endless optimization without consequences, NAMAKORIUM creates urgency through limited resources and constant environmental deterioration. Wasted time directly impacts overall progress, forcing players to balance efficiency with adaptability. That pacing keeps gameplay active and engaging without sacrificing strategic thinking. Environmental recovery becomes one of the most rewarding aspects of progression. Polluted areas gradually transform as restoration efforts succeed, giving players immediate visual feedback that reinforces accomplishment. Murky waters slowly improve while damaged ecosystems begin recovering over time. Marine life gradually returns to previously devastated areas, creating a satisfying feeling of progress beyond simply completing objectives. Watching environments recover gives meaning to management systems while strengthening the environmental themes at the center of the experience. Exploration contributes additional variety by encouraging players to discover marine life hidden throughout different regions. Collectible wildlife creates another progression layer that rewards curiosity and environmental awareness. Some discoveries reflect real ocean species while others introduce more imaginative creatures that reinforce the game's playful identity. These discoveries help environments feel more alive while encouraging continued exploration beyond primary objectives. Hostile elements ensure the game never becomes entirely peaceful. Corrupted marine creatures actively interfere with restoration efforts and introduce moments where quick responses become necessary. These threats create tension by disrupting established systems and forcing teams to adapt under pressure. Defensive coordination becomes just as important as resource management during larger challenges, helping maintain gameplay variety over longer sessions. Solo functionality remains surprisingly well supported despite multiplayer serving as the primary focus. Players tackling restoration projects alone receive adjustments designed to preserve balance and maintain enjoyable pacing. Individual play naturally creates a different atmosphere that emphasizes careful planning and optimization rather than communication, offering flexibility depending on player preference. Replay value receives additional support through varied environments and performance-focused objectives that encourage experimentation. Different approaches often produce different results, rewarding players who refine strategies over repeated sessions. The balance between accessibility and optimization helps both casual players and efficiency-focused strategy enthusiasts find something rewarding. Visually, NAMAKORIUM embraces a colorful and inviting presentation style that complements its environmental themes perfectly. Marine environments gradually becoming healthier creates satisfying visual progression while adorable creature designs help maintain the lighter tone throughout the experience. The contrast between polluted regions and restored environments reinforces player impact effectively without becoming overly heavy-handed. Its unusual premise may naturally create hesitation among players expecting more traditional strategy experiences. Those looking specifically for military conflict or direct competitive warfare may initially struggle to connect with its environmental management focus. Some of the strongest moments also emerge naturally through cooperative play, meaning solo players may not experience the full intended dynamic. However, Polyscape Inc. succeeds because NAMAKORIUM commits completely to its identity. Rather than treating environmental restoration as a simple novelty layered over standard strategy mechanics, the developers build an entire gameplay structure around cooperation, planning, and ecological recovery. The result feels distinctive in a genre often dominated by familiar formulas. NAMAKORIUM proves that originality still matters in strategy design. Through teamwork systems, meaningful management mechanics, and environmental storytelling delivered through gameplay itself, it creates something memorable without relying on convention. Players willing to embrace its unusual concept will likely discover a charming and surprisingly engaging strategy experience filled with personality and rewarding cooperative gameplay. Rating: 9/10
ナマコが食料不足で餓死する前に、海をお掃除してきれいにするゲーム。 マルチ前提のゲームだったが、ソロモードが実装されたり、 ナマココンテストというイベントが開催されたりして、本家、公式の優しさを感じます。 とにかくナマコが可愛いのと、音楽がゆったりしてるのと、 コレクション要素があるのと、キャラの説明が面白いのと、ゲーム部分以外にも楽しめる要素が。 最近 組んだPTとポジションをチェンジしてプレイできる機能が実装されて、 リトライ時により遊びやすくっ!! 入った順番関係なしに、ナマコさんの色を選べるとかあったら更に嬉しいかもしれない。 初見で情報を見ずに遊べば、 餓死と戦いながらなんとかリトライを繰り返しつつクリアするゲームバランスになってるとは思います。 慣れてきたら慣れてきたらで、何処に何を置いたら、お掃除の効率化が進むとかで、 タイムを詰めるプレイをするスタイルの人が多そう。 ウインドウモードと軽量化も実装されてるので、それもありがたかったです。 結構拡大もできるので、ナマコの可愛さも見れてそれも良き。
なーまこ なーまこ たっぷりなーまこ かわいい見た目と違って意外と硬派なパズルゲーム ステージがもっと増えると嬉しいです
二人でやるRTSとして10年に1本レベルの名作です 間違いなく楽しめます 圧倒的な可愛さと、情報量を抑えてとっつきやすくしている割にRTSの面白さは損なわれていません 難易度は普段ゲームやらない人にとってはちょっと難しいとは思います
