From what I can see from the physics, I think this pace of gameplay could be just right (I was expecting something faster like Quake, but then again the detail of these blocks can be crucial towards gameplay)
I'm also pretty surprised at how 'non-blocky' and moreso 'aesthetically pleasing' that first map looked. The grid size in the editor being smaller definitely helps
i am especially pleased to see the amount of zoom of the editor. My biggest concern was the "place 14 prefab buildings and your map is done"..
(although eventually this will of course be the case when you save block collections as new blocks, but still they remain your buildings)
the name and number of moods should avoid to be taken into consideration. Those are tests we do and some moods are imported from Canyon to test the reaction of light on some materials, but are not planned to be used. I would bet on 4 moods for Storm as well as Canyon.
