About
"—To fade away... was it hope for you and me, or despair?"
『Nientum – Op.Zero』 is a 2D action-adventure music game that combines platformer, action, and adventure elements.
Tune the stage through musical interactions and experience a unique journey to breathe life back into a theater that has settled in a gray stillness.
A theater once filled with songs and stories is now filled only with silence.
In this desolate place, Aleph and Liora, who have lost their memories, become the Director and the Actress to raise the curtain on a new play.
On a stage that is beautiful yet foreboding, warm yet sorrowful, they discover lost clues one by one.
What truth will they face in the final scene of this play?
The gems scattered throughout the stages are fragments of broken notes.
Use Aleph’s ability to tune them, play their restored notes, and restore stage devices to complete the preparations for the performance.
As platforming, puzzles, and action naturally intertwine, the theater begins to regain its vitality.
The Wizard of Oz, Cinderella, The Legend of King Arthur...
Familiar tales are reinterpreted, and sometimes twisted, into musicals that unfold before your eyes.
With each of Liora’s successful performances, a fresh glow of life returns to the theater. And their journey continues to the next act.
Nightmares and hope, wishes and despair, new encounters and farewells.
The fragments of memory lost by Aleph and Liora are revealed one by one, following your choices.
Depending on the direction of your choices, the end of the story takes a completely different turn, drastically altering their fates.
Please, join them in their journey and help raise the curtain on this strange play.
The stage is filled with music composed by renowned artists such as
Kagetora., Halv, and seatrus, delivering a deeply immersive experience.
The main characters—including Aleph and Liora—are brought to life by talented voice actors such as
Chika Anzai, Yuuki Takada, and Takehito Koyasu, vividly expressing the beauty and strangeness of the theater.
Director's Room: A space where you can record and view the various collectibles gathered while completing the play.

My Mind: The staging and flow is so cute, I can't wait for the next scenes! Me: THIS IS PEAK AND I HAVE AN EARGASM
공포로 변질되어버린 이야기를 재해석하여 고쳐쓰는 스토리를 담은 두 가지 타입의 건타를 혼합한 리겜으로 ost, 스토리, 게임성이 모두 좋았습니다.
まどマギ的な演出がイイ!音ゲーはオマケみたいなもので簡単。製品版が楽しみですね。

演出◎ 楽曲〇 ADV△ museの亜種です、演出にめちゃくちゃ手が込んでて一回やってみる価値はあります。 ただ完成版の半分くらい?のボリュームなのに七か月開発から情報がないし、このまま音沙汰無しだと今の値段では厳しいです。
現在できるとこまでプレイ済み いままでこんな素敵なゲームにあったことないくらいには感動した 仕様はミューズダッシュに近い感じでストーリーモードは曲に合わせて演出や物語が進行していくのでやってて楽しい それと何といっても曲が素晴らしい!製品版が出たらサントラをぜひ出してほしいくらいドはまりした 少しでも気になる人はぜひプレイしてほしい
2026年9月6日時点でのアーリーアクセス版の評価です。ストーリーとキャラは現時点で不明な点が多いため今後に期待ですが、ストーリー上での劇場の表現がとても気に入りました。視認性が悪いことは確かですがその分の世界観は描写されています。特に各章のボス戦が好きです。個人的にノーツの判定は甘めだと感じました。
Short and Sweet story focused rythm game. Between the low difficulty of the story and the gorgeous visual / audio design it itself honestly felt more so like a stage play of its own rather than a video game at times. Gameplay is simple with only two keys (high and low notes), its technically serviceable but mostly takes a back seat to deliver the stage plays and story. Free Play is available but on pure gameplay merit there are better alternatives. The Plot is delivered in visual novel style dialogue as well as the events of the plays themselves, and despite a few odd translations in English, the writing, soundtrack and illustrations combined for a very enjoyable experience. Since we currently only have one linear snippet i cant comment on the story as a whole nor the impact of any future branching paths. One thing i am worried about is the mention of eventual price increases in the EA section of the store page. At the time of writing there are 5 chapters, totalling to a little over 2 hours of gameplay. Since the stage counter goes up to 10, a full playthrough of the game would round out to ~5 hours - maybe a little more. The current price (20€) is good in my opinion, but any more is going to be a tough ask for most people considering we are looking at a very short indie game whose developer only has one other proper game under their belt.
极致的音乐与演出,神!,期待后续内容
〇全体的な感想 ・音楽はもちろんのこと、「見せ方」がとってもいい音ゲー 〇良い点 ・「見せ方」がとってもいい ・ゲームの大まかな内容としては、劇を舞台にしたリズムゲームと言う感じ。 ・2人いる主人公の内の片方が舞台装置を動かして、もう1人が劇をする…と言った感じの流れになっているのだけれど、それを音ゲーの枠組みとしてとても上手く見せている印象。 ・舞台装置を動かす側のパートでは、ランアクション+リズムゲームと言った形になっている。(とは言え特別な操作は必要なくて、ノーツに合わせて叩けばちゃんと動いてくれる。一定回数失敗したり特定部分でミスすると戻されるっぽい?) ・そして演劇のパートに切り替わると、舞台装置が動作して話が進む。(こっちでも操作が必要になることあり。近いものだとシアトリズムFFにあったEMSっぽい感じ…かな?) …と言う流れを音ゲーの枠内でとても綺麗に表現してる。音楽と画面の動きがマッチしているため、聴いていても見ていても楽しめる作りになっていて、そこが個人的にかなり好きなポイント。 ・BGMのクオリティが高い ・BGM自体のクオリティも全体的に高く。先に書いたように展開ともマッチしている印象があってとても+の印象。 ・シナリオも〇 ・シナリオ自体も演劇をベースにしながらよく出来ていた印象。 〇気になる点 ・一部視認性はちょっと気になるところあり…って感じ ・一部の箇所にて次にどのノーツを叩くのかが分かりにくいところがある。一応次に叩く必要のあるノーツはその周りにリード線(ノーツを囲んでくれるような枠がでる)みたいなのが出て教えてはくれるのと、使用するボタン自体は少ないので操作自体の複雑性は殆どないんだけどノーツのペースが速くなってくるところではちょっと視認性面で気になるところはあった。(次に叩くノーツが光ってくれたりすると嬉しい…かも?) ・遅延調整はやっておいた方がいいかも(設定画面から「シンク調整」って所があるのでそこから行けます)です。私はやっていなかった関係か、後半ステージのペースが速いノーツが多いところで結構ずれを感じたので(直したら結構良くはなった気がする、それでもほんの少しだけ気になるところはあったけど…私のリズム感の問題の可能性も捨て切れないので何とも)…。
