unknown! i saw that set
you were playing really good for the most part
but you should go that extra distance to make sure nana's dead, ESPECIALLY when you're in the lead. it really makes the difference, and even if you get bair'd for doing an extra shine to kill nana it's well worth it if you live (and arguably even if you die!)
generally you wanna keep your eye on the blue one (which you did really well), but when the opportunity arises definitely go out there and make sure nana's dead
like on dreamland, you wasted a whole lot of opportunities to kill nana, and for only like 1 nair on popo that sent him to the other side of the level where you couldn't edgeguard him
i'll do more later
