The problem is the game is too big now. If I remember the downloader is used to bypass a size limit to the apk.About Android ports..... here is an older version of full game without downloader
Google Drive
Maybe you guys who want a android version can try installing this, and then copy the game folder from a latest PC version and overwrite the files on the phone(pad)
I didn't try this method myself, if it doesn't work, try unrpa the pc version, and try overwrite again.
