OneShot 3D

OneShot is a puzzle and adventure indie game developed by Future Cat and published by Degica. Based on a 2014 free version, it was released for Steam on December 8, 2016 and on itch.io on March 12, 2020. Both its gameplay and plot involve metafictional elements; the game has been described by the developers as having "the world [know] you exist". Some of the game's puzzles involve interacting with the operating system outside of the game application. The player is a separate character from Niko, the protagonist; in the game's story, both characters arrive in a unfamiliar world which has been deprived of its sunlight, and eventually aim to restore it by replacing its sun, a lightbulb, at the top of a tower. And please, go play the original game before playing this.
