Giantess Spa is a 2D adventure built in RPGM by Lucifer and Lilith Synd, using 3D CG artwork. You play Lucas, a police detective investigating disappearances of men in the City where he lives. Thin clues point toward a new business called Giantess Spa, run by cruel women who seek a female domination society and treat men as slaves. The story is presented as a prologue, with multiple endings and a focus on humiliation.
Development is ongoing. Version v0.4.1 was released on January 15, 2025 for Windows in English, uncensored. The update adds new main menu music, a completed Size 2 map, new Sadira dialogue pictures from a giantess perspective, and 53 new images. It also introduces two challenging events involving Helja and Sadira, unlocked by failing a shrinking chance event with Trish. More Size 2 content is planned for the next update.
Developer's description
You are Lucas, a detective of the local police department investigating the mysterious disappearances of several male individuals, happening in the City where you always lived.
Not many clues are found, whoever is doing this has been hiding their traces really well...
But, being one of the best Detectives of your district, you have still managed to at least get a direction in which to investigate... Several clues seem to point to a specific building of a new business in town, a place called Giantess Spa...
Little do you know that the Women waiting for you are cruel and ruthless Dominatrixes, planning to create a Femdom Society, and consider men as pleasure tools and slaves...
Will you be able to survive the Spa and bring the truth into the light?

LexiTV2025-01-19★★★★★
Giving it 5 stars... not because it has no issues, but because of the sheer quality of the game. Art: Good, more of a realisistic look, overall quite decent. Content: There are 5 (not counting pairs) different goddesses / goddesses…
Goose690692023-05-02★★★★★
It specializes and focuses heavily on scat, waterplay, facesitting, enslavement(you can't leave the building and become a powerless prisoner). It targets some extreme fetishes and hence is a very unique game. I personally loved it because there aren't many games…
