you'll like it, even if you don't like remakes.
I also like the music, it's reminds me of super smash bros. melee. even the controls remind me of super smash bros. melee. they changed the music from the original tho, they made it cooler. the bosses are also the same BUT they are just a little bit harder, which is a good thing because kirby games tend to be to easy.
they best new feature of the game is the hard mode that appearers after you beat the game with 100%. kirby games are easy so it makes the game more fun. there is also a boss battle thingy where you have to fight all the bosses with only 6 life points, it's really fun. and the very best part is when you beat the hard mode with 100%, then you get to play with meta knight... that's right you control meta knight and play with him instead of using kirby!! over all Kirby: nightmare in dreamland is perfect in every way...
