An Upside down chess board

wow i guess you were bored because this makes no sense lol...THATS NOT UPSIDE DOWN THATS JUST BLACKS VIEW (i play as black 90% of the time)
knight e3 isnt mate and pawns dont move backwards =( ... O.o
it is mate because all the pawns are 1 sqaure from queening they're all on the 2nd rank not the 7th rank that why the hint was upside down cause it isnt as it appears.
it is a funny puzzle I have in one of my books
