Thanks for putting us in the video, Jupiter! I doubt you'll see this because I can't seem to tag you or reply to your comment, but the description explains the movement (see below). You can only turn or walk forward on one turn--you can't do both at once like in other games!
- Directions are in world-space, like the compass rose. You can only walk a tile in the direction you are facing. If you press a different direction, you will use that turn to rotate and face that new direction. Moving or Turning each take up a single round of gameplay.
