I can say the exact same thing as I did in the Super Mario Bros. review, but there's one thing I want to add: The level design. It's absolutely horrid and I would've gone mad without save states (played with Nintendo Switch Online), especially since it feels like you can't predict what's to come. There were some levels I had to look up how to solve because the solutions felt unreasonable. The original Super Mario Bros. was at least fun, but this one doesn't really do it for me. It's only going to get half a star lower since it's basically a hard mode in my eyes. Overall, frustrating game without save states and not really a good sequel.

Edit: I'm lowering the score because I feel like my original score is too high compared to some other games in its original rating and is slightly under Super Mario Land for me.
