Wow, what a beautiful little dioramic adventure demo. I really love the aesthetic you've got here. The dynamic shadows and inuitive, gentle controls give this a particular feel that I like a lot. It threw me off a bit before I realized this wasn't designed for use with the HMD clip. It might be nice to give users an option to specify whether they're using the table-top setup or HMD clip.
Either way, this stands out as a very high quality VR experience and I'm looking forward to the full release.
