The Futa Experiment

The Futa Experiment Step into The Futa Experiment, a casual adult visual novel where you run a quirky base to create genetically superior Futa creatures. Make non-linear decisions, manage loyalty, and keep the girls happy to stay.

The Futa Experiment

The Futa Experiment is an adult-focused visual novel that mixes stylish visuals with sandbox-style freedom and mature storytelling. In this game, you play as a desperate man or woman exploring a living, changing sandbox world—overseeing a strange base built around creating “genetically superior” Futa creatures.

Your choices matter: you’ll decide how much your girlfriend is involved in the project, and you’ll use mind-control mechanics to keep her loyal. At the same time, you must manage the risk of getting pulled too deeply into the addictive allure of the Futa experience.

Gameplay

This is an unusual VN with a non-linear structure and a repeating gameplay loop. You’ll be expected to complete tasks for the girls; as their desire rises, they may request sexual favors. Your goal is to keep most of them satisfied—once per week, they’ll vote on whether you’re allowed to stay.

If you allow your girlfriend to remain, she won’t just “wait in the background.” She’ll work alongside you and slowly grow closer to the other girls. This doesn’t happen instantly; it unfolds over time as they gradually try to persuade her. You’ll also have the option to let the girls spend intimate time with her, which can increase the likelihood of further sexual encounters.

Features

• Unique storyline:

  Follow a character who gets the chance to work at a mysterious complex. The facility’s goal is to build a genetically superior race, and your progress depends on managing relationships and keeping the girls content enough to maintain your position.

• Character customization:

  You can choose to play as a man or a woman, tailoring the experience to your preference.

• Varied scenes:

  The game includes many scene types—intimate interactions, invitations, and hypnotic events—each with different levels of engagement and excitement.

• Repeatable content:

  Some scenes can be replayed with variations, letting you experience different outcomes across runs.



• Engaging animations:

  Smooth, polished animations—especially during intimate moments—help the visuals feel more immersive.

• Android compatibility:

  The latest release adds an Android version, so players can download and enjoy the game directly on their devices.

What You’ll Get

• Balance your relationship with your girlfriend while handling seduction attempts from other Futas.
• View a range of adult scenes, including anal, vaginal, and oral sex, plus mind-control-related scenarios.
• Customize your character’s appearance and explore parts of the complex at your own pace.

Developer Notes

Hello everyone, and welcome.

This build is a semi-demo / alpha. It contains far more content than a typical demo (including anything around version 0.1). I’ve been working on it for about 4–5 months.

A cheat option is included in the Player room. Enabling it can help you reach some scenes faster if you choose to let your girlfriend stay. (This isn’t recommended unless you mainly want to see scenes sooner.)

I’ve done extensive playtesting, and I’m hoping there aren’t many bugs left—but since the project includes roughly 13k lines of code, it’s possible something was missed.
