Reviews

“"I let my guard down—this is the real deal. Might even be a benchmark." The controls are excellent. The UI and effects (like fluids) feel incredibly polished and well-crafted. The “skin poke” feature with soft mesh deformation is really satisfying, and you can drag with the left mouse too. It gives off an instant immersive vibe that breaks dimensional walls. Everything moves smoothly, menus behave properly, and rotation/movement is stable. Unless the state management is rock-solid, this level of polish is hard to achieve... This game definitely clears that bar (which I personally find impressive). This feels like something that could only be made by someone with deep experience in gameplay and development. I honestly think it could serve as a model for future creators in this genre.”

“"Even acrobatic positions—there are infinite possibilities!" Most 3D sex simulators use a system where you choose preset motions, but in this title, the player can make the character take any pose using IK. The level of freedom and visual quality is like nothing before! Actually, the price is so low it feels like a bug. Beyond positions, expressions like ahegao and especially the fluid effects are incredible. It doesn’t just use particles—it genuinely looks like thick white fluid. I’d give it 100 out of 100, but if I had to be picky, IK angle adjustments are tricky. You can save a pose, but only one, so re-adjusting every time felt a little tedious. Being able to pre-save multiple poses and switch them with one click would be awesome. I’d also love to see additional hairstyles, backgrounds, and pre-registered pose collections sold as DLC. Being able to jump straight into sex is great and convenient, but it can also feel a bit dry, so I’d really like some extra voice packs (before, during, and after H-scenes).”

“"Sweetness with a well-crafted body." As expected from a game featuring a popular 3D model, the body is beautifully made. The system where you remove clothing piece by piece gives a strong sense of undressing and feels very good. There are three basic positions, and you can fine-tune the body’s placement, letting you create movements that look shy or wild—adds a nice touch of playfulness. There are also four facial expressions, and combined with body motion, I felt I could create most of what I imagined. I really liked that the game wasn’t just carried by visuals—it showed real care and quality.”

◆This is Just the Beginning! Future Plans for the SEX Simulator Project◆

This is the first step in a grand SEX simulator project, with plans to expand as follows.

*Since controls and gameplay will differ greatly, these will likely be developed as separate titles, not updates to this one.

(1)SEX Simulator (*this title): 3D motions and effects for immersive SEX experience

(2)SEX Simulator VR: Supports VR, with head/hand/hip tracking in-game

(3)SEX Simulator 2D: Emotional responses change based on mood and flow, using AI in engines like RPG Maker

(4)Wife Simulator: Add romance sim elements where everyday life and conversations affect affection and sexual reactions

(5)LIFE Simulator: A full town sim where you can freely love and have sex with multiple characters

The goal is to create a game that simulates “life itself,” where players can enjoy SEX freely.

Ultimately—when humanity is traveling the stars across generations in massive spaceships,

this game will be implemented aboard ships to enrich the sexual lives of the crew.

When that becomes the norm in the future,

this game will be remembered as the first step in humanity's next stage of evolution.

Be part of this historic project—experience the first step yourself.

*However, if this title doesn't sell well, the project may end here.

If you believe in this project’s potential, please consider supporting it by purchasing this title…!
