Yeah sorry I had committed the cardinal sin of pushing a broken state to the repo.
There was a lot of really, really bad code in there anyway so just as well 
If you pm me your github username I can add you as a collaborator so you can have a look.
The plugin has some pretty fundamental limitations at the moment, namely it only supports single state goals, and just takes the first plan it can find rather than looking for an optimal one.
I’m building out a decent sized set of actions for the game module (it’s a shooter type game), then once I’ve got a decent sized graph to work with I’ll start completing the planner functionality.
