Well, here goes nuffing...

Since we're not allowed to post direct links, you'll have to solve a series of easy puzzles to find the beta:

1) Find the website github dot com.

2) Find the repository named "odf/Antonia.Polygon-1.3".

3) Click on "Releases" on the right side.

4) There should be only one release, which is named "Antonia 1.3 beta1". Click on "Assets" to see the available downloads.

5) Both "source code" downloads contain exactly the same files. Pick your favorite format and download away.

The download is fairly big (43MB) because with SaintFox's kind permission it includes the Toni Polygon texture by her and Digital-Lion.

I hope you enjoy.
