Interesting that you caught "Far East and Indian influences", so did I. In fact did you notice how Amanita Design's founder Jakub Dvorský is pictured in the closing credits? (I won't spoil here for anyone that hasn't yet gotten to the end of the game)
Also, and I'm sorry that I can't find which interview this was mentioned in so don't take this as a statement of fact, but I seem to recall reading that JD has traveled in India. If that's true then one can assume that he picked up some of the "influences" of Indian culture while there.
