It's definitely not bang your head against a wall frustrating. Just a lot of different things to do to make it work.

People have said mobile works but I honestly haven't tried it yet. All my devices are too old to work with webgl.

Actually playing doesn't work well on mobile, because you can only "left-click" and can't view inventory, chat, or do much of anything other than attack the cow and pickup the leftover entrails. Ah well, still a neat idea.
