Interesting game, visually looks really great. As for fun, for me personally, exotic controls of arrows to move and WASD to rotate the camera in fixed steps was REALLY painful. Like every second I was playing this game I was wishing I could use my mouse...
Other than that it sure is an interesting experience, though outside of trying to survive I'm not sure what I'm supposed to do.
Also, why I can't walk through grass? That feels artificial and immersion breaking
