i severely dislike how, when two bibites make contact, the defending bibite is just launched across the screen, ending all engagements as quickly as they began. i wouldn't consider this combat.
my dominant species in my world right now gets to around 30u with jaw/attack strength around 450/220N if that means anything.
also, if one bibite can comfortably fit through the other's throat WAG/bite size, they should just get nommed whole. this could open up for an internal parasite build or make bibites more likely to become predators, and give bibites a chance to escape if their attacker dies soon after.
