Demo 10 has no hotspots. The prototype simply ends, which is how a lot of real prototypes end too: at the edge of what has been designed. Testing a flow doesn't need every screen, only the ones on the path being tested.
The frame above is drawn at the original proportions. Each dashed box sits where the 2009 hotspot sat and links to the same screen it did then, so the tour can still be walked end to end.
