It plays quite well. Had Nintendo released a VCS port like this us kids with our 2600s would have loved it. Actually, Nintendo were the first ones to keep their games exclusively on their systems... Atari, Coleco and Mattel ported their stuff. I guess that in 1986 people could still actually hope for an official port as that was the common way of doing things.
