Played on hard mode for the first time which is, in theory, harder because there's more enemies throughout levels and they introduce later world enemies earlier on. But, the real reason it's hard is because of the frequent slow downs from the game struggling to handle all the enemies on screen and their various animations along with Mario's and, while it's not an ideal source of difficulty, it did make it more challenging. I really just love this game. I think it offers some really unique spins on the series canon even if it's a touch too easy.
