Critics praised the game's art direction, narrative elements, and depiction of anxiety and depression. It would also see a release on Nintendo Switch, Xbox One, Xbox Series X/S and PlayStation 4 with added content in June 2022. It was eventually released for macOS and Windows in December 2020, six years after its initial funding. After a successful Kickstarter campaign, the game was delayed numerous times and experienced several development difficulties. Omori is based on the director's webcomic series of the same name. Prominently portraying concepts such as anxiety, depression, psychological trauma, and suicide, the game features strong psychological horror elements.

The game's turn-based battle system includes unconventional status effects based on characters' emotions. How Sunny and Omori interact depends on choices made by the player, resulting in one of several endings. The player explores both the real world and Sunny's surreal dream world as Omori, either overcoming or suppressing his fears and forgotten secrets. The player controls a hikikomori teenage boy named Sunny and his dream world alter-ego Omori. Omori is a 2020 role-playing video game developed and published by indie studio Omocat.
