NES game was one of my favourites - it was extremely easy. I like the idea of the a remake like this - its good to see it has remained faithful to the original, but it just looks a little dull. I'll pass for now.
For the SSF2HDR they effectively traced the existing sprites, whereas here they created new animations from scratch, so (not sure if you've played it yet) it feels a lot like the Nes game, but the SSF2HDR disconnect isn't present here.
