The Worlds are pretty much the same as NSMBDS but the addition of the spin jump, propellor mushroom, penguin suit and ice flower make the experience more fun. The Koopaling castle fights can be fun at times and the Bowser Jr airship levels and fights in World 4, 6 and 8 and the Bowser fight at the very end of the main game are really good. However, after you beat the main game there’s a bonus world with eight challenging levels, one of those is 9-7 which might just be my least favourite level in the entire game as its really unfair and cruel to the player at times. Also, I didn’t even bother rescuing Toad outside of World 1, but I did collect all the Star Coins and get every Secret Exit and the Ghost Houses are nowhere near as annoying as they were in New Super Mario Bros. U and the difficulty is perfect. Overall, I had quite a fun time playing this game and I’ll definitely play it again in the future at some point.
