You can cancel spells with the escape key. I have 2 questions that stem from this.
1. Is this a good enough way if you had known the information beforehand
2. Are there any ideas you have on how to better indicate this mechanic to the players?
oh. I mean good enough if I had known, yeah probably. But esc to me is a key that usually opens a menu or something, not a key that's used as an input. Making spells cancel by moving seems more intuitive.
