glitch( i guess?): I try to change and keyboard input, amd the [ok] buttom is now [???] and i got no way to turn it back(even if i redownload the game, the [ok] buttom is still [???], cause i guess there's some system save outside the game?)
Open data.ini (found in AppData/roaming/Skantish) and delete the section labelled Configuration. (Just find where it says 'Configuration=', then delete that and everything following it up until 'SaveGame='. It will all be on a single line in Notepad.)
