Widescreen resolution

By default, game renders at 1280x720 and then upscales the content to match selected resolution. It's possible to raise the internal resolution to 1920x1080, however most 2D assets are done for 1280x720 and thus are upscaled regardless.

Notes

  1. 1.0 1.1 1.2 When running this game without elevated privileges (Run as administrator option), write operations against a location below %PROGRAMFILES%, %PROGRAMDATA%, or %WINDIR% might be redirected to %LOCALAPPDATA%\VirtualStore on Windows Vista and later (more details).
  2. 2.0 2.1 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>/202530/ in addition to or instead of this directory. The app ID (202530) may differ in some cases. Treat backslashes as forward slashes. See the glossary page for details.
