rain is the enchanting tale of a boy who chases after a girl with an invisible silhouette. After discovering that the girl is being hunted by ghostly creatures, he embarks on his own journey into the mysterious world of rain to save her. Upon entering the world he discovers that he has also become invisible and he must learn to navigate through the unknown, using the rain to guide and protect him.

Throughout rain, players control the invisible boy, leveraging the unique ability to appear in the rain and disappear under cover to advance through the storyline. However, just like in the real world, players must understand that at times what they are able to see isn't everything and they must use their imagination to interact with the environment and solve puzzles, and to help them along their journey to safety.

The world of rain is shaped by introducing a unique and harmonious blend of vivid fantasy artwork and realistic images. Combined with the expressive sound of falling rain, splashing water and the reflective nature of puddles as the invisible boy passes through, the game is designed to awaken the sense of uncertainty and solitude inherent in every player.
