Empty game menu

Try to remove your player.eco file. To get there, open "run" via system search and type "%UserProfile%\AppData\LocalLow\Strange Loop Games\Eco", which will get you directly to the location of the file. Let me know if it worked.

Thanks, the issue seems to be caused by the "Continue" button refering to a singleplayer game that no longer exists. (E.g. after deleting the game you played last, for whatever reason it got deleted)
