The concept of the game has a lot of potential and is quite impressive how big the playable area is.
But the main mechanic (moving and running) is lacking. It doesn't give the player enough decision. The only thing you can decide is to run or not, and as soon as enemies appear the decision turns into "run or die".
A little bit of more variety for the NPCs would have been nice. Maybe some could be friendly all the time, or take some time to notice that you have something valuable.
