Thanks for the comment. It is indeed something I've been considering. In fact, lots of the optimization done here is to move the logic away from the game objects , which should enable the flow you've described.

I ended up not doing it in this iteration because:

- cocos2d's custom shader support is kind of poor, especially documentation is pretty much zero

- the dot is not "purely" visual. For example you can trace and highlight a resource's movement. This is not a blocker per se, but requires more work
