Is this your preferred method of asking questions and posting bugs from the playtest?
I noticed during my first playthrough the fighters (Swordsman, Archer, Mage) stopped responding on the 5th wave. Is this intended? They were alive and a blue check appeared above enemies, but they would not defend.
I also noticed at about the same point a mage I had sent before the wave to fight an enemy at the mine had become immortal, taking no damage from two different mage enemies at once.
