We started developing this game based on a few simple ideas: "Let's make a 3D game," and "Can we portray the stories and world we've imagined as a video game?"And finally, the game is here.
We hope you have a wonderful experience traversing this strange world and unraveling the story, as well as taking a deeper look into concepts such as purity, ugliness, joy, and anxiety - some of the complex and constantly moving parts that make up the human psyche.
