What is a pony? A miserable pile of friendship.
This group is for the game Ponyvania: Order of Equestria by ZiggyLung Studios. Their website is http://ziggylung.com and the game as of the end of July 2018 is out for download. It's a side-scroller in the vein of Koji Igarashi's Castlevania games. The current wiki is here.
So I need to thank whoever added my most recent story to the group. I would have myself if I knew it existed.
