Overview
The Neuronauts is a sci-fi harem adventure for players who enjoy speculative worldbuilding alongside their adult content. The tone leans curious and conversational rather than dramatic.
Story
Humanity's first contact with an alien species overturns expectations: these aliens are open, affectionate, and organized around a bonobo-like social structure rather than monogamy. Fascinated by human culture, they draw a group of humans into an extended cultural exchange, trading customs, curiosity, and mutual attraction as both species learn from each other.
Gameplay
Players guide a male protagonist through this exchange, exploring a sandbox of locations and conversations while building relationships with a cast of human and alien women. Dialogue-heavy scenes carry discussions on psychology, communication, and daily life alongside the romantic and sexual threads, with rendered scenes and animated clips marking key moments. Progress unfolds through an ongoing structure of chapters rather than a single linear path.
Features
- Speculative xenobiology woven into the setting, including alien anatomy, social customs, and ecology shaped by their home star
- A large ensemble cast spanning human and monster-girl characters
- Rendered 3D scenes with animated clips throughout
- A replay gallery for revisiting scenes
Changelog
v42.5k
- 900 new renders.
- 43 new videos
- Spelling and grammar should be improved for the entire game.
- Sadly translations will not come out until likely next release due to a formatting glitch I can't yet figure out, discussed in my previous devlog. I'm pretty happy with this update, and the next update is half written because a lot of major plot points I've been sitting on for at least half a year, come together next time. See you again at the end of october!
- Note to android users: The game has gone beyond 4Gb which is its limit without a special workaround, I didn't have the time to investigate for this specific build. There are now 2 android versions. If you are new to the game download week 5. Week 5.5 version has all of the videos before week 4 deleted. You can still play the game but there is no video. I hope to figure out the workaround by the next build and have one file to download to run it. Thank you*
