are there any gamers where you play as an animal or beast?

other than futmutz

Yes. There’s a (probably incomplete) list in this IFDB poll.

Emerald is there a way to download and play these games? i cant figure it out.

The titles of the games on that list are links to pages about those games. Each game’s main page has a download link or links in the upper right corner. For common formats, there is also a “Show me how!” button that should give you even more specific directions on how to play that game.
