Tried it a bit and its interesting. I was overwhelmed immediately by the 3D aspect. As mentioned before, it would be great to have some buttons to reset the camera to some specific settings. Additionally it would probably be a good idea to hide/show only some layers? I guess it would be hard to come up with great UX to make it intuitive and easy to use, but the amount of points in front of me makes it hard to grasp all possibilities.
Chess for instance is already tough on a 2D plane if there still lots of figures on the board.
Anyway, i didnt find any bugs while playing around. All the pieces did what the descriptions said.
