Not being able to remember anything about a title in a series you may generally consider memorable might be a indicator that the entry wasn't up to par. Just because it had tougher platforming challenging at the toughest stages doesn't mean I had to enjoy it as much as NSMB Wii, which I overall enjoyed much more because I played it with friends.
Totally, I know that NSMB DS is fine mechanically and I remember having fun with it at the time, but I can't remember a single specific level, and I don't even know if I can remember all of the worlds.
Grass, desert, swamp, mountain, volcano, island/ tropical... guess I can remember all but one. But yeah, not a single individual level comes to mind. The jumping momentum thing was frustrating a few times in 3D Land but many of the levels are very creative and memorable, and while obviously both would be ideal, I'd rather have memorable levels and slightly faulty physics then spot-on physics and levels I'll forget a month later.
