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 or do much of anything other than attack the cow and pickup the leftover entrails. Ah well, still a neat idea.
