This story will be about a guy who fell into the world of a giantesses against his will. This world is very similar to an ordinary human one. However, all technologies of that world are associated with magic. Every giantess can make a magic. But each giant girl needs an individual magic amplifier for the full use of her abilities. And this magical amplifier is a specially selected man from the human world.
The main character of the novel is the guy who got into the world of giantesses instead of his friend by mistake. The guy's task is to return to his world.
The attachment contains the CENSORED build of the prologue for Windows and MacOS (The build for MacOS hasn't been tested, because I have no MacOS devices). The app will be updated as it's developed.
UNCENSORED builds and the description of my activity are publishing on my Patreon page.
The temporary character graphics was created by Helen Giantess. The music was taken from the standard library of Visual Novel Maker. Backgrounds were generated in Room Planner Design Home 3D.
A few words about translations into English and Japanese. I don't know English well. And I don't know Japanese at all. I used Google translator, so many errors are possible in English and Japanese versions of the texts. All of them will be fixed in the final version.
