Omori (stylized as OMORI) is a 2020 role-playing video game developed by indie studio Omocat.[a] In the story, the player controls a hikikomori boy named Sunny and his dream world alter-ego Omori. They explore both the real world and a surreal dream world to overcome their fears and secrets. How they interact depends on choices made by the player, resulting in one of several endings. The game's turn-based battle system includes unconventional status effects based on the characters' emotions. Prominently featuring concepts such as anxiety, depression and trauma, the game has psychological horror elements.
The game is based on the director's Omori (ひきこもり, hikikomori) webcomic series. After a successful Kickstarter campaign, the game was delayed numerous times and experienced several development difficulties. It was eventually released for Windows and macOS in December 2020, six years after its initial funding. Plans for a Japanese translation and ports to the Nintendo Switch, PlayStation 4, and Xbox One were later announced post-release. Omori was acclaimed by critics, who lauded it for its graphics, narrative elements, soundtrack, and depiction of anxiety and depression. The game was favorably compared to games such as EarthBound and Yume Nikki. Omori went on to be nominated for several awards, winning DreamHack's "Daringly Dramatic" category in 2021.
