Q: The controls: The movement's nice. Casting spells is done though a reasonably quick popup menu interface. My only complaint is that the minimum number of degrees that you can turn seems a little high. I find myself oscillating back and forth a lot, trying to aim precisely at some poor monster for a long Magic Missile.
A: Using left shift with the movement keys and you can line yourself up perfectly every time. For some reason this isn't in the docs.
