When the player is selecting a target for a spell, the range of the spell is now displayed in form of a circle. This is an important usability improvement, because there was no indication which targets are in range and which are not.
Another usability improvement I added, are damage numbers which indicate
the element of the damage with their color. Also, ethereal damage is
now shown with a "mp" suffix and healing with a "+" prefix.
I added a rotating heptagram to the circle as a little gimmick. I am not sure if I am going to keep it. It seems distracting without adding much.
