Lemon Industries

Lemon Industries is a puzzle game inspired by Severance, a weird TV show. In this game you work for Lemon Industries as a novice data sorter, and your task is to process files stored on a special computer. Since not much is explained to you, try to find clues, observe, research and feel free to experiment.
Important: the game contains no spoilers and there are no actual references to the TV show! The visuals are similar but the content is not.
