Well given the amount of time, I think they've done a job well done on this one, been trying to make models here and there ,and exporting them to unity, takes a lot of time and effort...(wait...are they using the ViNo Toolkit? )
Actually this could be a huge game. If you've played any of the other games by them, you would realize they could throw all of those stories plus more into this game for one big collection. It's actually pretty smart on their part.
And AFAIK, this build is still testing. Probably not supposed to be too worried about completion just yet :b
