I don't know if it's appropriate here, and my opinion may not matter a great deal as I'm a relative newcomer to the whole of "Graal Online"- but from my humble viewpoint, your version of the server was one of the most creative and engaging I've seen in all the hosted worlds I visited.
The graphics are wonderful and charming (though some of the terrains were a bit busy just in understanding what you could walk over/around and what you couldn't). I say keep up the amazing work - some very obviously talented, creative and "outside the box" thinking has gone into this game.
