I'm trying to use the mouse to aim. In theory, this will let me fire off the straight lines, and on diagonals.
But when I move, the mouse pointer moves.
What I want: Robo-tron style move with the key, and aim/fire with the mouse. Let me run to the right while shooting to the left.
I can't. Not with keys to move and mouse to aim, anyways.
Yes you can. Use WASD to move. Assign fire to left-click and shield to right-click, if you need to.
