It's honestly just okay in my opinion. It seems like people either love or absolutely hate this game, but I can't help but find myself gravitating somewhere in between. One hand, the concept of "SMB1, but harder" isn't necessarily a bad thing to me considering I've beaten the original too many times to count (including several times under the influence of our world's magic mushrooms...heh) and I can appreciate that concept. That being said...the hammer brothers spam, the dumb wind gimmick and springs that launch you at inconsistent heights and speeds are really god damned annoying and keep me from coming back to this game as much.

Although unofficial, I think there are a handful of hacks out there nowadays that do the whole "Mario...but for super players!" thing far better. SMB Special: 35th Anniversary comes to mind as far as the original game goes. Bandicoot's Super Mario World hacks (especially Crown Tale which I loved cringe story aside) also fit this bill nicely. None of those games get as hard as this one, but offer a comfortable step up in challenge IMO.
