Using the keyboard for movement it appears the character cannot move diagonally. Movement seems to be via the keyboard arrow keys (no mouse for movement) and with the keyboard you can only go up, down, east and west. What's odd is enemies can attack me diagonally and when I hit the "x" key to explore the character will move diagonally but I can not do so manually. Normally, that not a problem but on my current map the entrance to a new level can only be reached via diagonal movement.
It this a bug, design limitation or am I doing something wrong?
