Im gonna try.
First you download the game from here and then, you open the file.
Second you need to extract the file since is compressed
Once you're done with that u have to open the non compressed file, and you will see 5 "files"(not sure how to call them) one of them will say apk or something like that and will have Freddina on it's left side. That's the actual game. Hope this can help you
