oooh i think you're so wrong about that, in my opinion 54.8 is way harder than 54.6

an easy way to finish 54.6 with probably 1 death is to start bombing all the top bananas/pears down from the top left side of the box,, after that a lot of the enemies down there will be dead. then you go inside the box (probably using the death shield) and straight to the top where you can play bomberman,, shouldn't be that much of a problem and you should die AT MOST 2 times there
