Very much enjoyed the test, obviously lots of work to be done but I'm very impressed with the core mechanics and the feel of the game.
I'm sure something along these lines is planned but it would be nice to be able to mark your map for points of interest. Maybe even being able to share locations or sell them in item form for people to mark?
I hope you intend to keep NPCs (friendly ones / towns etc) to a minimum or non-existent. Player driven economies really can be fantastic.
Look forward to the next test keep up the good work.
