No problem, glad to help out.
Question for you, because I don't really know how the plugin architecture works… What parts of the user interface are under your control and what parts are not? I'm trying to think about possible improvements to the usability/intuitiveness of the game but I don't want to suggest things that you cannot alter.
Also, I just also spotted a small typo: In the wide button bar just under the play area there is a button marked "Ressource" which should only have one "s" in it.
