Remove satanic symbol used on Star Stable(mostly children's game)

On the game site Star Stable, a game frequented by horse riders/lovers around the world, there is a Satanic symbol on part of the game. Two attempts have been ignored by senior executives in the organization. Here is a sample of the sort of letters that have been sent:

Dear Fredric Gunnarson,

I enjoy playing a safe, stable, family-friendly game, such as Star Stable. Many Adults, and Youth, find it fun to visit, and play, on this site. It helps to foster many fine traits, such as kindness to animals, group cooperation, and enjoyment of natural surroundings. Here is a recent remark on this game site:

“Star Stable is one of my favorite games of all time, and is definitely worth a play. There's something to offer for all ages and the continuous new content keeps you engaged. If your child is under twelve, monitor them, but this game is safe for young children as well.”

On one quest, regarding Jarls Tomb, where I had to open the Moon door there was an evil graphic. Once I had it open, I went inside and seen another door with a star on it. In the middle of said star there was an inverted pentagram. I know full well what this symbol means. I will include a screen shot of what I’m talking about. I find this highly offensive and feel that many others would feel the same.
"A reversed pentagram, with two points projecting upwards, is a symbol of evil and attracts sinister forces because it overturns the proper order of things and demonstrates the triumph of matter over spirit. It is the goat of lust attacking the heavens with its horns, a sign execrated by initiates."
I have sent an email on this issue online. There was no response.
