The concept is really interesting, making them punch each other is also something nice as well as trying to avoid all the bullets, it's a nice twist. Also the hidden key to (Dodge, dash) that gets you outside the map (if intentional) will be good to have another key to return, cause i managed to get them kill each other, but once you are outside the map they stop following you since they can't understand you are nearby, which leads to having them not fighting each other also when they are in opposite sides of the map. In any case it's fun overall, and the idea is really something else.
