  1. 1.0 1.1 File/folder structure within this directory reflects the path(s) listed for Windows and/or Steam game data (use Wine regedit to access Windows registry paths). Games with Steam Cloud support may store data in ~/.steam/steam/userdata/<user-id>/906100/ in addition to or instead of this directory. The app ID (906100) may differ in some cases. Treat backslashes as forward slashes. See the glossary page for details.
  2. For instance, ← Backspace is not listed among the Controls but used to back out of objects inspection; some of the functionality of Space is remappable but even when fully remapped, the game will require its use to close the SamOS interface.

    Closed the launcher, removed its folders and launched the game without issues.
  2. 2.0 2.1 Verified by User:Rose on 2019-05-21
    Screenshots taken at 5760x1080, 3840x1080 (both custom), 2560x1080 and 1920x1080, then compared.
  3. Verified by User:Rose on 2019-05-23
    Played through the game at 2560x1080 without notable issues.
  4. Verified by User:Rose on 2019-05-21
    Used a custom desktop resolution of 3840x2160, got to select it in the menu, and it lowered the FPS.
  5. Verified by User:Rose on 2019-05-21
    Found this out by extracting the game files.
  6. Verified by User:Rose on 2019-05-21
    75 FPS on a 75Hz monitor with RivaTuner and Shadowplay FPS counters.
  7. Verified by User:Rose on 2019-05-21
    Tested by checking whether NVIDIA ShadowPlay would display FPS.
  8. Verified by User:Rose on 2019-05-24
    In my testing, quickly moving the mouse results in little change on the screen, while moving it slower results in much more distance traveled.
  9. 9.0 9.1 9.2 Verified by User:Rose on 2019-05-23
    Tested with an Xbox 360 Razer Onza controller.

  11. Verified by User:Rose on 2019-05-23
    At 2560x1080, the SamOS hints are partially cut off but visible. At 5760x1080 there are no signs of them.
  12. Verified by User:Rose on 2019-05-21
    It works, and it seems to be the only way to access the extra keybindings.
  13. Verified by User:Rose on 2019-05-21
    This appeared when inspecting a document. A No Code developer said this on Discord: "It's an X inside the backwards arrow - that's what backspace looks like on most keyboards"
