This seems to be working if slow on my computer

- depends on wip/sfml+ which has a note that joystick input
  is not available but might not be too much work and I don't
  know if relevant for this game

- this is the last tagged version of OpenHexagon and is 7
  years old but there has been some work upstream since

- I have written a wrapper script which sets up a
  $HOME/.openhexagon dir with symlinks to the assets etc
  it kind of works but could be better, particularly
  need to look at what happens to config files and/or if
  it is only the Profiles/ folder which needs to be written
  in which case that could be ~/.openhexagon

- I added the Assets which the wget-assets.sh fetches, but
  openhexagon crashes because the assets don't contain a
  pack.json file. However, openhexagon-2.0-preview is older
  than the SSVOpenHexagonAssets on github

- the game itself bombs out sometimes complaining that it
  is too slow. is this simply to do with lack of GL ?

- there was a complaint about network connectivity needs to
  be checked
