You need to make an option to lock your hero in place. Im tired of accidentally losing a 15 min battle because I didn't notice I didn't have mana to cast.
Was stuck on level 14 forever, finally broke down and looked at a walkthrough. I was making it harder than it was because I couldn't see how the pieces looked, an option to make all but 1 piece wireframe or invis would help 100 times over.
