Erosphere is an erotic sci-fi visual novel by bdot.labs, built in Unity with 2D CG artwork and point-and-click adventure gameplay. You play a male protagonist who wakes in his room and meets an attractive woman claiming to be an alien. She seeks help to stop a catastrophe affecting Earth. After unforeseen events his body changes and he ends up on a spaceship, joining a crew of nine attractive sexually inexperienced women as the only male aboard. The game mixes management and corruption themes in a space setting.
The current v93.2 build, released September 6, 2026, continues in early access, with early releases available through Patreon. It runs on Windows, Linux, and Mac, is in English, and is uncensored. The latest update optimized main-menu and asset loading times, addressing long boot-up delays caused by unnecessary asset checks. It also improved character loading so expressions and poses change only after images load successfully, reducing previous flicker.

After a series of unforeseen events you undergo noticeable changes to your body and end up aboard a spaceship. Now, you must join
a crew of nine attractive and sexually inexperienced women
in their travels through space and find your place among them as the only male on board.
Early access
to early releases is available on Patreon.
v93.2
Optimized loading times of main menu and some assets. This was a big issue previously because the main menu load took forever to boot up. I finally found the option that was doing that. It was some unnecessary asset check (CRC) that is on by default even though it is only useful when having some kind of cloud thing where the assets are retrieved from. I'm happy that this is finally resolved since I'd imagine I wasn't the only one annyoed by those stupidly long loading times.
Character load now works better. When changing expressions or the pose of a character there was a flicker before while the expression or pose image was loading. Now the expression or pose is only changed after the image or images are successfully loaded so the flicker shouldn't occur no more.
There are automatic saves now after each chapter. These saves can be loaded (if present) in the chapter select menu. So if you played through a chapter before it will ask you if you want to use your own chapter save or the default one (the default ones are just the ones I created for myself to jump to different points of the game). There was also an error with how these were created but that is also fixed now.
Performance issues fix for hunter vision and other visual effects. Apparently there were some larger issues with the visual effects I was using. Especially hunter vision. This should be fixed now and hopefully perform better (haven't tested on a lower performance system yet).
Some smaller bugfixes and polishing changes.
Hints can now me deactivated/activated in the settings.
Alien compendium included as a preview for act 2.
Version save is now separate from quicksaves.

the camera controls have been reworked. you can control the camera via wasd now. There's also r and f for zooming in and out and q and e for rotating (rotate doesn't work in adventure mode) alt is also for zooming/rotating the camera with the mouse and space is for moving the camera with the mouse
the camera resets to its focus position if it hasn't been moved or touched for a while

I have tried kinda hard to like this game, it feels right on the edge of something... neat? My thing? It just circles around and never really gets there (or anywhere, a theme, if you will). There's a sandbox tag…
smallst82026-03-27★★★★★
I played this game for an hour hoping it would eventually open up or go somewhere. It doesn't Pros-art is good. There is even a mechanic where if there is a female png on screen you can jiggle her tits…

I really enjoyed playing the game an will keep an eye out for future updates. Minigames need more work, card game becomes boring and repetive real soon and the fighting minigame is not impossible to beat but lock players out…
