That is something diffrent, really nice shader! I really like the contemplation the strange world vibe, really relaxing. Music was great too. 

I had a few technical problems.

- I've seen z-fighting(wikipedia page) on the mountains, 

-I fall from the map, maybe there could be mountains that you cant climb. (at first I thought map end was a sea, and I was amazed though :D)

- after I fall from the map I didn't know how to restart.
