This fight may be a bit difficult because instead of 3 v 1 it's 1v1. CURRENTLY Tenna only has 3 attacks and you can only attack, use item and defend, defence also heals a little bit. Z to select and right arrow to move selection arrow keys to dodge attacks (Feel Free To Remix) :D
Currently updating frequently to make it better UPDATE 1: You can actually damage Tenna now UPDATE 2: You can heal by using items and Tenna has a smash cut attack now when you use items UPDATE 3: Defending is now an option and Tenna now has a third attack also made some better graphic changes
