Really interesting concept and I really appreciate the tutorial not many games have that. My only issue is that ALL THESE CHUDS don't want to fight the battle. Seriously though, Idk if im stupid but I bought a new zone, and a sniper enemy appeared AND NOBODY WANTED TO FIGHT HIM. So that zone was just worthless for awhile.
UI Idea: Have the characters stack, so theres not just a massive bar at the bottom with flooded characters. Idk if its easy but it was a bit hard to find the plI already bought.
