I've seen some music of popular classical pieces that are transposed from a more difficult key to an easier key (such as Gb to G major) to make it easier to play for the average 'duffer'.
Indeed, but if this was the intention here, it has failed miserably.
Easier to sight read perhaps, but much more difficult to play.
Or at least, it was when i tried it and i count myself as the average duffer
