Hi! Thanks for the recommendation. I do indeed plan on submitting Crashtastic to the Greenlight process, I just need to finish up a new trailer!

I will have a demo in the near future.

Looking into this.

I have no current plans to do this. I will review sometime in the future.

I have a free camera mode in the replay viewer, but I won't be adding one for the realtime simulation.

I do plan on adding a better follow camera.

At some point in the future I will be adding this to the editor as well.

Can you describe the problem you are having? The problem described above shouldn't be an issue any longer. 

As soon as Unity releases the 4.0 version of the engine, I will be upgrading and should make it available shortly after. This will hopefully be in a few weeks.
