I have made quite a bit of progress lately adding turreting, spectating and an interactive ball. Each of these features are in the early phases of implementation but close to finished. I have included some images below illustrating turreting and and animated gif the interactive ball in action.
I will need to delay thing a couple/few more weeks. So very close, so stay tuned, things should pick up the pace of the next week or so..
Interactive Ball

One online player turreting another similar to Continuum.
