Haha you bothered to make a disclaimer!
Nice game ! In which engine if I may ask?
Well, the disclaimer is kind of part of the story, else we wouldn't have added one. It would be a bit weird if that was an actual disclaimer, haha!
The engine is Ren'Py. It's one of the most well-known engines for Visual Novels and is nice to work with. You can easily expand its functionalities with python. There should be a link in the "credits" and "about" sections if you want to check it out :)
