Does the demo still work because my computer doesn't recognize the file?
Which file is it Windows or Linux?
FOR WINDOWS installed it to your ideal location
and for Linux just extract it.
same here, strange file type for a game.
What is its extension is it in .exe or zip
neither, just a blank file.
Then rename it to (Nikhoj.exe)windows or (Nikhoj.zip)linux. Then it should work ,it might be the itch's storage or server error for providing a blank file.
Thanks, trying the game now.
