I'm with newt on this one,
Poor documentation on tile orientation (insertion of blocks as well), drive change problems, ect. It look's appealing to block building for platform levels, which in my personal opinion, goes pretty smoothly by hand after some experience. No additional Asset management functionality that I saw, other than block placement.. (although, I admit I didn't spend much time with it after seeing that interface
May be appealing for seamless block building and quick snapping of scene layouts, and seems very beginner friendly. I'd like to see where it grows in the future.
