Lock disengaged. The heavy cell door opens into the silence.
The facility has fallen, now transformed into a labyrinth where desire and malice swirl.
A world of madness where the boundaries of flesh are violated and rewritten.
The pitiful souls left behind must resist — either surviving the aberrations prowling the darkness or having their bodies claimed by them.

Hi!
I just wanted to let you all know there’s no shame in pirating this game. Whether it is due to censorship, bans, lack of money, or any other reason – we still respect you. ^^
If there are any issues with the game, don’t hesitate to file a bug report.
Hope you enjoy the game!
Let me know if you want this post to be taken down.
Your game is incredible and I hope you’re proud of it, it’s genuinely one of the most atmospheric Eroge i’ve played since Nyctophobia 1, Explorer of The Golden Planet and Anthophobia <3
woahh, one of the best hentai game that I ever played. The quality is not lacking, the gameplay is fun, the difficulty is not very hard and it was really rewarding when you progressing (because you can unlock more skins when progressing and exploring).
Also somehow I got ICEY (normal game) vibe from this game, altho ICEY is just hack and slash with movement and combo as the core of the game, but CelSector need aim, accuracy, and patience, also somewhat combo with the switching guns feature.
Anyway, this one is one of the best quality of H game that I ever played. The gameplay is fun and casual (because the enemies is not that hard, just dont lower your guard). The art, animation and outfits (skins) is very detailed and neat.
This is really a ionate project, I can feel it.
Prob I will the dev when I can.
If you wanna know my score for this game, then it will be 10/10.
I like the gameplay, the detailed animation and arts, also the difficulty that is balanced. Everything is good, well except for some guns that is really underwhelming in late game.
And you, who is reading my comment and still thinking about ing this game or nah. IT AND PLAY IT! Also don’t forget to the dev if you like it. They are generous enough to not taking down this post.
