      Please purchase the game on https://olofson.itch.io/kobo-redux

      Once you have downloaded the file, please use the following command

      Alternatively, install the "koboredux-free" package, which replaces the

      Kobo Redux is a frantic 80's style 2D shooter, inspired by the look and
      feel of 90's arcade cabinets. The gameplay is fast and unforgiving,
      although with less of the frustrating quirkiness of the actual games
      of the 80's. A true challenge in the spirit of the arcade era!
    '' + optionalString (!useProprietaryAssets) ''

      This version replaces the official proprietary assets with placeholders.
      For the full experience, consider installing "koboredux" instead.
