note: the file goes into trash when downloade

I know my way around managing compressed files on most computers just fine, mac included. The real issue though is due to it (The Unarchiver) extracting the game as a folder and not a ".app" file, easily achieved by adding the missing ".app" part at the end of the folder's name. Your note was amusing to me.
