While it is undoubtedly one of the most influential games ever made, I don't really think it holds up that well on a gameplay perspective. The momentum physics feel like you're constantly running on ice, luckily there's not too much platforming to worry about but for some parts it can definitely be upsetting. Most the levels themselves end up feeling pretty repetitive without much variation. The hammer bros are a particularly frustrating enemy that certainly poses more way of a threat than any other that it feels feels like a nuisance, especially on 8-3.

I probably wouldn't recommend this if you're actually looking for something fun unless you use save states on it. As an experience to learn more about game history it's fine enough though.
