Erosphere [v17.15.30.4-2k] [bdot.labs]


Overview:

Erosphere is a erotic sci‑fi visual novel with point-and-click adventure gameplay. As the main protagonist you wake up in your room where a bright light wakes you up. When the light fades, an attractive woman appears in its place. Claiming to be an alien, she asks for your help to prevent a catastrophe with universal repercussions on Earth.

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.

The game features animated scenes and is available in both 2k and 4k versions for different resolutions. The 2k version is available publicly, while the enhanced 4k version can be accessed through Patreon, SubscribeStar, or on itch.io. Early access to all releases is also available on these platforms.

Developer Notes:

Does this game really have jiggle physics?
See More
Hell yeah!
Why do you use AI Art?
See More
Believe me I get that AI art is considered problematic by a lot of people. I consider myself an artist too (yes i mean the non-AI-reliant kind) and as such I’d rather abuse AI than be abused by AI. You can’t stop AI art after all so we have to evolve somehow. I’ve spend 40+ hours on single artworks before and I know the effort that goes into an art piece but I also know how tedious this process can be. AI allows me to spend more time on overall quality by cutting a lot of the time spent on that tedious part of the process. Also this process isn’t as straightforward as ‘press button get artwork’ I still have to make major decisions where the art should be headed and correct a lot of stuff for consistent character design and stuff like that.
Whats the difference between the 2k and the 4k version?
See More
The 2k version is free and publically available here. It features 2048×2048 gallery images.
The 4k version is available through patreon or subscribestar subscription. It features 4096×4096 gallery images but is more costly in terms of performance and hard-drive filesize.
Why do you warn about performane on low-spec PCs? Isn’t this a visual novel?
See More
Basically this is because I was too lazy to get comfortable with live2D or other animation software so I wrote my own animation framework. This framework kind of does animation in runtime and thus requires better than low specs. I’m sure i can optimize this some more but for now this needs to suffice. Also this framework gives me a bit of flexibility to do some cool effects. You can also turn those off if you don’t think they are cool – that should also improve performance.
What does that 4. something version mean?
See More
I wanted the version to reflect how much content is in the game rather than have a version that basically tells you that the game is not finished. So this is what the version means:
Basically add up the first 3 numbers and you get the number of items in the gallery.
4 Scenes – All animated except for the first intro scene with multiple sequences.
5 (female) Character Renders (includes different outfits)
4 Cards
0 Minor Version (for bugfixes)
2k/4k Resolution of Gallery Images (2048×2048 or 4096×4096) – 4k version is available through patreon or subscribestar subscription
Why are these cards in the game and what do they do?
See More
The cards are part of a game system that isn’t fully implemented yet. Meanwhile you can enjoy the visuals.
What’s the deal with the transformation tag?
See More
It’s only minor transformation but if you want to spoil it:
See More
Transformation is from chubby male to muscular male.
