Yesterday I was casually doing the EX bosses for my sister because she was having a hard time on them. I did them in order of Encore! Encore!, Killing two Birds, Breaching the Contract, and No More Bad Guys (despite it the last one already being done). I managed to do them all -No More Bad Guys without dying. And I only died on No More Bad Guys cause I was distracted. So I went 3 for 3 on the EX bosses and I had no clue what I was doing for the majority of the fights. I did use the Switches assist mode however because I’m not that good at the game.
