Thanks so much for checking it out and for the feedback! The healers were originally going to keep their distance and heal allies, but we ran out of time, unfortunately.
The units walking backwards was a half-implemented feature where if your side's "knight" unit was still alive and inactive, they would walk the sword to them. The knight would then advance down the battlefield. Unfortunately, it's not working as intended, and units will just walk backwards to their deaths. ^_^;
Thanks again for the kind words!
