This is frozen base act 2 where you are using eggmans chair that flys, there are some pink ufo looking enemies that you need to destroy, you have a row at the top and at the bottom while dodging enemies coming towards you, my strategy was to take the bottom ones out first and when the background changes focus on the top ones, you will then fly to space and fight 2 boss one after the other, the first one raises his opening to shoot him but fires some green stuff that can bounce off the wall behind and the next boss is eggmans face with steel balls on the outside and some green ones on the inside that change colour when being hit, he also fires shots up that come down where you are, my strategy for both off these is to just hold A and just focus on dodging the enemy fire.
