[Hey - sorry for the late reply. I either missed a notification of this post or did not get one.]
We have been all-consumed with the Game Developers Conference (GDC), getting some funding and getting awesome people to become part of our team.
We are in this for the long haul. We will be doing another round of the closed beta soon after GDC and after we incorporate the results we will move to open beta.
There is still one day left at our booth (#141) at GDC and it has been amazing so far including great discussions with several Epic Games staff.
If you are attending GDC and would like to ask questions or see a demo please barge in and join the crowd - I’m the guy with the goatee who never stops talking and waving my arms around.
