Necrosphere Deluxe is a minimalist Metroidvania platformer developed by Cat Nigiri, released in 2019 for PlayStation 4, PlayStation Vita, Xbox One, Nintendo Switch, and PC. The game's defining constraint is its two-button control scheme, through which players navigate an entire interconnected world without access to a conventional directional input beyond those two inputs. The experience is compact in scope but notably demanding in difficulty, designed to challenge players within a tightly constructed environment typical of the Metroidvania genre. The "Deluxe" edition brings this stripped-down yet punishing platformer to a broad range of platforms, maintaining the core concept of achieving meaningful exploration and progression through an intentionally restricted control set. Its small scale and sharp difficulty curve make it a focused, unconventional entry in the genre.
Necrosphere is where you go when you die, regardless of being good or bad. You don’t see other people around there. You don’t have anything to do, except waiting for eternity As soon as Agent Terry Cooper hits the Necrosphere, he learns about the portals that can take him back to the world of the living (also called Normalsphere), and his quest to escape the afterlife is set.
