The idea is amazing! The model and the environment are really good. I had a few troubles with it though:
- it would be nice to have alternative methods of movement. Smooth sliding gives me motion sickness very quickly and it is one of the major problems with VR in general, not only for me. Teleportation and stepped movement would really help.
- Tutorial or some kind of instruction would help. As your description says, it is pretty difficult to fire the thing, and it seems to even more difficult to figure everything out on one's own.
- There was a guy in british uniform, who was running towards me very slowly. He ran to stop exactly at my position obscuring my view completely. If I move away, he follows me to my new location. The only way to be able to do anything is to keep moving all the time. It does not seem possible to interact with him. Who is that guy? Is it possible to make him stand somewhere aside?
