What is NaissanceE about?
NaissanceE follows the story of Lucy, a lone roamer who finds herself stuck in an enormous, surreal building. The game begins with Lucy being chased by some invisible entity before falling through a trapdoor into a massive, labyrinthine world. NaissancE is a platformer/Exploration game available for free on Steam, and is directly inspired by NIHEI Tsutomu’s BLAME! Both this manga and the game it inspired feature gigantic, agoraphobic superstructures, giving them an amazing Backroom vibe that I believe you might like.
