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.
Free Play Mode: A dedicated mode where you can enjoy tracks built with the rhythm-action expertise of Quesera Games, separate from the main story.

很棒的演出,原创曲也很好听,希望以后也能保持

玩法有点像muse dash但不会觉得生搬硬套,20首原创曲也很不错,就是太少了
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。

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)…。
연출이 너무 좋아요 무대 연출로 어디로 갈지 몰라서 체감상 조금 어려운 것도 있었는데(1층 2층 노트있으면 번갈아 뛴다던가) 일단 체력이 넉넉해서 안 죽고 지금까지 난이도까지는 할만 했습니다. 그리고 리겜 잘 못 하는 편이라 첫풀콤을 내지 못해서 숨겨진 걸 보기 위해 항상 2회차이상 여기는 풀콤이 기준이 아니라 모든 노트를 치는게 좋았어요. 뭐가 다르냐면 전판에 내가 못 친 것만 쳐도 해금됩니다.(다 안 치면 체력이 없어지니 적당히 쳐주기는 해야함) 하나 아쉬운 건 다시하기를 자주 하는 편이라 다시할 때는 대사와 컷씬 부분에 스킵이 있었으면 합니다...다시 볼 수 있는게 좋기는 한데 숨겨진 걸(뒷면) 보고 싶어서 n번할 때는 넘기고 싶더라고요. 그것빼고는 진짜 다 만족. 재미있게 했습니다
音游玩法的剧情推动型游戏?演出非常华丽,收集音符(打歌),布设场景助力完成舞台剧演绎,大概是这样的感觉。剧情有全程配音和中文翻译,虽然翻译质量一般,但是连演出时的歌词也翻译了,至少态度很好。剧情只出了一半,也看不出来什么,目前是结合了很多经典故事来作演出,像灰姑娘,竹取物语之类的。 玩法就是类muse dash的两轨音游,不过剧情模式里加上了很多场景和人物的互动,观感很不错。 自由演奏模式里就是纯粹音游了,现在只有10首歌,全原创,一些是剧情里的完整版,一些是约作曲家写的原创歌了,每首歌两个难度,总体难度不算很大。 现在内容太少了,仅2.5h的主线,很多功能也没有(像文本回顾,cg鉴赏,重新开始主线等),ea半年了也没啥更新。kalpa,ea一年直接更新2.0完整主线,希望这部也能这么效率吧。 未来可期
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.
