Where can I find this free online game?

I don't know the name of it, but it started with all players starting in the center of a map, and each person chose to go down, left, right or up. You would gain support from other monsters in the game. It used to be on gamesdomain.com. They sold out a while ago. This game used to be in the games castle they had on there. If you know where I could find the castle....that would help also!
