Mario game with too many new enemies, level themes, playable entities, sound effects/music tracks etc. to list. The new powerups were a little underwhelming and I wish they had 1/5th of the new enemies and used them in unique combinations with each other because most of them only show up for 1 level, don't provide much challenge because you're supposed to be tutorialized on what they do, and then you forget about them because they don't show up again.
