The STARNAUT himself, and no one else, carries this torch burning bright, encoded inside his mind and in his heart, and to remember is to care, about each and every bit of it. Truly an enormous responsibility, by any measure.

Copiasu
“All right, reset time! I‘m feeling great!”
The 8th Designer Baby created by Stella. Driven by the dream of one day becoming a Starnaut and meeting Stella, he continues fighting. However, he actually received that title from Stella right from the start—he simply is too shy to claim it himself. With his incredibly positive personality, he charges forward fearlessly, no matter what kind of enemies may stand in his way.

Stella
“When in doubt, use your fists!”
The guide to Copiasu’s game journey. Originally created as the central AI brain of Seven Nights, she takes on an automatically generated form when emerging to the surface, which can change slightly each time. The form pictured is how she appeared in her first meeting with Copiasu, and is the version of her that Copiasu trusts and cherishes most as his beloved Stella. Stella tries to maintain this form for Copiasu as much as possible, although she finds it a bit chilly during the winter.

“Hmm... WONDERFUL!”
The physical manifestation of Wonderful chat, an AI chatbot created after Stella. He once served as an aide to Copiasu, but has since devoted himself to serving as a support role in his original form as a chatbot AI. You may occasionally spot him in his physical form as he runs around the stage with Lost Data in hand. If you spot him, make sure to give him a punch!

3Dで繰り広げられるヴァンサバライクのアクションゲーム この作品が目についた人のためにまず知らなければいけないのは これは操作キャラに迫る敵を、複数の武器を使って駆逐していくヴァンサバライクのゲームです そこに、ロケットを打ち上げるという捜索ミッションと酸素時間という時間制限を組み込んだ タイムアタックの要素も混ざった計画的進行をゲームに組み込んだアクションゲームでもあります 武器はコインを獲得して強化、そのコインは武器の強化やステータスの強化による殲滅力により効率も変わるので 強化もこまめに必要 そして、その強化コストのコインが無いとミッションであるロケットが打ち上げられないというリスクも伴い リスク管理を楽しむゲームでもあります ここまでくるとすごく難しそうには見えますが、実際操作して遊んでみると結構ヴァンサバしてます 一部のステージはタイムアタックやミッション要素が強かったりもしますが 多くのステージは基本的に武器を強化して迫る敵を殲滅してロケットを打ち上げてクリアするゲームです 武器にもいくつもの種類があり、強化すると敵をバンバン蹴散らせれるようになり爽快 慣れてきたステージではもうクリアできるのに限界まで強化して遊んでしまったりしてます ステージは結構広いですが、ニトロジャンプというリキャストスキルを使ってフィールドを縦横無尽に飛ることができます これは移動にも回避にも使うことができ、それがアクションの要素を出して セガのソニックのような爽快感も生み出してくれます。 2Dフィールドが多いヴァンサバライクを3Dでやってみたものに興味があるなら一度触ってみてほしい ちなみに、ヴァンサバの面白いところの一つであるキャラの変更は 特殊効果を持つマスク(被り物)を変更として表現されてます いくつもの違う見た目のキャラを操作して遊ぶのも魅力と感じてる人はやや物足りなさがあるかもしれませんね そこに関してはこの作品のストーリーなので仕方ないのですが そして、この作品は同じクリエイターの作品のエルシャダイにかなりつながった内容になってます 前の作品を触ってなくても後悔はしない内容にはなってますが その作品の多くの用語がこの作中に出てきます スターノート世界観に少しでもさらに興味が湧いたのであればエルシャダイにも触れてみてもいいかもしれませんね このスターノートのストーリーテキストが好きならばきっとそちらの作品も気に入ると思います
操作はカンタンだけど奥が深くて、どんどん先が気になる。 毎回展開が違ってるから何回もやりたくなる! スキマでテンポも良くて遊べていいかんじ
Mythical Concept STARNAUT is a fast-paced survival action game developed and published by crim Co., Ltd. that blends roguelike structure, auto-shooter combat, and a stylized science-fiction mythos into a tightly focused yet highly replayable experience. Built around short, intense runs and constant forward momentum, the game places its emphasis on adaptability, build experimentation, and the satisfaction of surviving overwhelming odds. From the very first moments, STARNAUT makes its intentions clear: this is a game about movement, positioning, and smart growth under pressure rather than precision aiming or complex controls. The premise casts the player as Copiasu, a uniquely engineered astronaut tasked with restoring fragments of a shattered Earth across multiple dimensions. Humanity’s legacy has been scattered, symbolized by Ω Rockets that must be launched to reclaim oxygen, progress, and hope. While the narrative is not delivered through lengthy cutscenes or dialogue-heavy sequences, it provides a thematic backbone that gives emotional context to the endless combat. The idea of rebuilding a lost world through repeated, dangerous excursions adds weight to each run, framing failure as part of a broader journey rather than a simple reset. Gameplay revolves around wave-based survival across dozens of compact stages. Weapons fire automatically, allowing players to focus entirely on movement, spacing, and situational awareness as enemies flood the screen from all directions. This design choice makes STARNAUT immediately accessible, but it quickly reveals surprising depth as the game introduces its extensive weapon and upgrade systems. Players can equip multiple weapons simultaneously, selecting from a wide roster that includes projectiles, beams, explosive effects, and contact-based attacks. Each weapon behaves differently, and synergies between them can dramatically alter how a run unfolds, encouraging constant experimentation. Progression during a run is driven by collecting coins from defeated enemies and spending them at in-run shops that offer weapon upgrades and suit enhancements. This creates a compelling risk-reward loop, where players must decide whether to invest in immediate survivability or gamble on long-term power scaling. Enemy density steadily increases, forcing players to refine their build choices and adapt their movement patterns as the screen becomes increasingly chaotic. Even small decisions—such as which weapon to upgrade or when to reposition—can determine the success or failure of a run. The roguelike structure ensures strong replay value. Stage layouts, enemy compositions, and upgrade opportunities vary from run to run, preventing the experience from becoming rote. Losses feel instructive rather than punishing, as each attempt teaches players more about enemy behaviors and effective build combinations. Outside of runs, meta-progression systems gradually unlock new weapons, characters, and options, giving players a steady sense of advancement even when individual runs end prematurely. Visually, Mythical Concept STARNAUT adopts a vibrant, stylized sci-fi aesthetic that balances charm with intensity. Environments shift across dimensions, keeping stages visually distinct despite their compact size. Enemy designs range from playful to menacing, often masking dangerous behaviors behind deceptively cute appearances. The screen frequently fills with effects, projectiles, and enemy swarms, yet the visual clarity remains strong enough to support readable gameplay, which is crucial given the game’s reliance on constant movement and awareness. Audio design complements the frenetic pace with energetic music and crisp sound effects that reinforce feedback during combat. Weapon sounds are distinct and satisfying, helping players intuitively understand their build’s effectiveness even amid visual chaos. Subtle narrative elements, such as recurring characters and collectible lore fragments, add personality without slowing the pace, giving the game a sense of identity beyond pure mechanical challenge. One of STARNAUT’s strengths lies in how well it balances accessibility with depth. New players can enjoy the immediate thrill of survival combat without mastering complex systems, while experienced players can dive deeply into optimizing builds and experimenting with weapon synergies. Runs are short enough to fit comfortably into brief play sessions, yet engaging enough to encourage “just one more try,” a hallmark of effective roguelike design. Overall, Mythical Concept STARNAUT stands as a polished and confident entry in the modern survival shooter genre. It does not attempt to overwhelm players with narrative density or mechanical complexity, instead focusing on delivering consistently engaging combat, meaningful progression, and strong replayability. Its combination of accessible controls, deep build variety, and thematic cohesion makes it appealing both to newcomers and genre veterans. For players who enjoy fast-paced roguelike experiences built around experimentation and survival under pressure, STARNAUT offers a compelling journey through a fractured universe that rewards persistence, creativity, and adaptability. Ratng: 7/10
This game has the potential to be thee next massive "Survivors" genre game; Truly such a GOAT'd team <3
Почти год прошёл с релиза, но я так и не прошёл её. Я не хочу, чтобы эта игра заканчивалась. И поэтому я в неё буду играть столько, сколько хватит, и может быть пройду. Эта игра - прекрасный пример творческого стремления и энтузиазма. Сама по себе игра является Vampire Survivors в 3D, но более динамичной. Куча отсылок к El Shaddai, разнообразие оружия, миллиард врагов и пердолинг вашего компьютера. Игра реально отличная и настоящий хидден-гем 2025-ого. Crim это та студия, которая способна творить и удивлять, но единственная проблема у них - финансы. Если можете, то купите игру, даже по скидке. А Crim и Саваки Такеясу я желаю всего хорошего, буду с нетерпением ждать его новую игру.

アーリーアクセスからプレイしていますが、アクションが苦手でも楽しくプレイしています! エルシャダイを知っていると楽しさが倍増しますが、エルシャダイを知らなくても楽しめます。 因みに家族はこのゲームからエルシャダイに興味を持って、ゲームや小説を読みま始めました!(^^)!
幻想的な雰囲気。エルシャダイプレイヤーに親和性の高い世界観とプレイ感覚。とても良い。
エルシャダイチームのヴァンサバ系3Dアクション! いろんな武器とヘルメットの力で、立ちふさがる敵を蹴散らしていくのはとっても気持ちいいです!!世界観もとっても素敵なので気になった方はぜひ! 一緒にスターノートになりましょう!
操作性良し。初期スピードこそ遅いものの、強化次第でどんどん早くなるのでステージを進めるのが楽しくなる。 特にニトロダッシュ・ニトロジャンプの爽快感は非常に気持ちがいい。
