I don't really know how it was coded but my best would be shortening the "Missed" bit. I think it makes your attack go in a bit of a cooldown. And you could also make the, I think it was this, short burst 1 second instead of 1.5 because I felt that made me go out of the rythm when I wanted to chain cast it. Didn't mention but I loved the spells, especially Death Ray. I though it was supposed to reveal itself once I play a little, turns out I was supposed to discover it. Again really cool concept.
Out of topic, the unresistible urge to spam Zoltraak.
