Why is donkey Kong bonanza dlc a absolute joke

So finally finished donkey Kong bonanza and it is a great game but the dlc it does nothing for the game it's as if the Devs went we need a dlc for donkey Kong bonanza and we have no ideas let's remove stuff from the main game and make it a dlc and charge £20 emerald rush is a reskin of Donkey Kong bonanza main games instead of gold it's emeralds literally don't see the point in it
