Could you allow a form of attribution that fits better when several artists are attributed? Like, including "Amon Interactive Ltd - www.amon.co" in a list of people responsible for the art? I like this, but that particular attribtion method would sound awkward and... well, a tad pretentious if it's being used alongside many other art assets, which I imagine would be the case pretty much always.

Thanks! No need to make credit optional, just wanted a more elegant way to do it. :)
