This looks amazing but I'd appreciate an autoplay button or free walk + look, the scrollwheel monorail handcranking makes the exploration rather frustrating.
It's not even working on my phone (Android + chromium), just stuck at 100.
Tried it on a PC. It's close to useless, unfortunately.
Too bad, these other efforts elsewhere to create 3D models of ancient cities work fine both on a PC and Android tablets.
