About
Space is infinite. Can you even trust yourself?

Picture this: you wake up on a drifting space station, completely isolated in the endless void. The systems are barely holding on, and your only companion is the irresistibly intriguing Cassiopeia. Together, you’re forced to keep the station running, but there’s a catch—one of you isn’t human. And it might just be... you.

Explore the broken-down space station, dig into its mysteries, and uncover the truth about yourself and your enigmatic partner.
Isolation, tension, and doubt turn into an electrifying connection. Will you work through your suspicions, or will desire pull you into a whirlwind of passion and uncertainty?
🤖 Trust no one. Not even yourself.
The station’s AI hints at sabotage. There’s an android among you. The closer you get to Cassiopeia, the more you wonder: is she really what she seems to be? Or are you the one living a lie?
🌌 Is space your prison?
The station, the malfunctions, even your own memories—what if they’re all part of some twisted experiment? Who’s the real enemy? The void? The android? Or maybe... it’s you?
🚀 A captivating story that blends sci-fi, eroticism, and psychological tension.
🔥 Intense adult content with romantic and steamy moments that deepen the narrative.
🎭 Emotional choices and dilemmas that challenge your perception of trust, identity, and connection.
🌠 Stunning visuals and immersive soundscapes that pull you into the vast emptiness of space.
Can you uncover the truth before the station becomes your tomb?
Ready to face infinity?

實在沒有欲望全成就了,本地化毀了一切。故事其實就是圍繞男主身世和女主的背景展開的愛情故事,立意在黃油裡算比較有心的。 游戲性:點地圖找綫索解密,約等於無,成就有gal的選擇要素。 cg:無碼,3d,有動態10張,靜態十幾張,但都不是很精緻的3d,女主有種亞裔歐美人的感覺。 配音:約等於沒有,狗屁不通的英文,可以當作沒有,字幕機翻問題+配音沒有=劇情極難看懂。
Its ok i guess. Models are nice and the animations are good. But It took a while to get interesting.
« SEXSTELLAR » est un roman visuel pour adultes articulé autour de rencontres courtes et épisodiques dans une station spatiale. Le décor de science-fiction sert principalement de contexte. La narration reste légère. Les dialogues privilégient les présentations de personnages et la mise en situation plutôt que des arcs scénaristiques étendus. Les attentes en matière d’histoire doivent rester mesurées. La composante ludique est minimale. Le joueur effectue ponctuellement des choix de dialogue influençant certaines variantes de scènes. Aucun système de ressources ou de gestion n’est présent. La progression suit une séquence linéaire d’épisodes, avec des déblocages liés à l’achèvement. La rejouabilité provient des embranchements scéniques plutôt que d’une profondeur structurelle. La direction artistique constitue l’atout principal. Les designs sont variés et les animations privilégient la fluidité. Les angles de caméra mettent en valeur le point d’intérêt de chaque séquence. Les environnements se répètent, mais demeurent adéquats. La qualité visuelle dépend du matériel tout en restant cohérente. L’accompagnement sonore est simple. La musique s’exécute en boucle de manière discrète. Les effets sonores sont basiques. Le doublage reste limité. L’ambiance repose davantage sur l’animation que sur les signaux audio. Les paramètres et les volumes sont facilement ajustables. Les performances techniques sont stables. Les temps de chargement sont courts et les plantages rares. L’interface se montre claire, avec des menus simples. Le système de sauvegarde fonctionne sans difficulté. Des problèmes mineurs de collision et de posture peuvent survenir. Dans l’ensemble, il s’agit d’un produit de niche axé sur du contenu animé pour adultes dans un cadre de science-fiction. Les joueurs recherchant une narration approfondie ou des systèmes complexes resteront sur leur faim. Ceux privilégiant la variété des scènes et des designs stylisés bénéficieront de l’expérience prévue à petite échelle.

bought this for the lols, didnt get hard once 0/10
Gibberish voice acting. You can turn it off. No ability to set the name of the MC. No ability to move back in the dialog and no real incentive to read it. There's nothing to involve you. No narrative hook. Thus I clicked rapidly until reaching alleged decision points and didn't understand what I was deciding. But I doubt I was deciding anything. In short, no feeling of involvement in the story or the sex scenes which just appear almost without any context. It's like going to a porn site and randomly clicking on videos...except not as "interesting." 😜 Returning it for a refund. It feels like a shell of something, I know not what.
É um lixo, simplesmente, um lixo! Já joguei diversos jogos de put@ria e esse por sua vez é lixo porque? Não atende os pedidos, (SPOILER) A nave está bem dizer para explodir e a Android desgraçada quer fazer S3XO à todo custo! Esse jogo foi feito pra punheteiro e não para quem curti jogos com conteúdo e que tem uma ótima história, é só mais um lixo Hentai que só quer mostrar bunda e peito de início.

I don't see any Thai language interface.
