what do i do while extracting the file in the same location?
after downloading the new version, extract it using 7-zip or any other archiving software. Look for the old version of the game and move the new version to that location. If a message pops up that there already is a file with that name click overwrite or something like that. If it does not pop up manually delete the old version. I do recommend to use the itch app tho since it makes updating a lot easier
