Besides getting rid of the firebreather (I couldn't tell if that was supposed to be transformed Coco), I didn't see much use in either the punch or slowing down. I beat all 3 stages in one try just by aiming for balloon clusters.
I was left wondering what time period this is supposed to be. Is this Coco introducing Kanata to Sana right before Sana's debut? Cause they were only both in Hololive for 1 month, and that was 4 1/2 years ago.
