Combat that expands beyond kh1 with it being more fun, especially with the addition of the reaction which brings more life to the boss battles and the combat system allowing for more the music is a major step up from kh1 and overall the story taking more of a serious tone makes the story feel special and more interesting the only problem is the Disney worlds with them feeling like filler the world design is also a downgrade from kh1 but the hallway like world design didn't bother me to much overall great game and the post-game content is great.
