Although I am a bit late with it, I have a good feeling about this one. Most of my game mechanic is finished. On the picture you can see the graph of paths drawn out, red paths are active, blue are passive, and are activated, when you reach certain action nodes in the graph. You can see an action node, under the mouse, indicated by a spinning red circle. The filled red circle is you player, who travels over active paths. You can send him to an action node, by clicking on it. He will find the shortest way and follow it, until he reaches that node.
Now I need to replace the black background with scenery, red circle with a sprite, create animations for action nodes and some sounds all wrapped up as a neat puzzle. Right now I hope I can get one level together, after that the menu, and then maybe another level (my head is in the clouds).
