her tears were my light
The best visual novel game ever created. Highly talented game dev NomNomNami made this using Ren'Py game engine. It features the personification of three entities: Time, Space and Nil. Your choices will decide the fate of Time (the protagonist). Highly romantic and lesbian themes. Also, the soundtracks are awesome and almost had me in tears. Perhaps there will be a part 2 of this game.
The theme for "her tears were my light" is absolutely amazing for its ambient electronica. More visual novels need to be created in this way.
