The best of the NES Mega Man games I have played so far. First time we get somewhat of a story which was a welcome change in my opinion. The one-screen sub screen was a very welcome addition as well. What a huge improvement compared to the previous three games that was.
I enjoyed most of the stages and most of the bosses. The bosses were a more difficult than they were in the previous games but they were fair. No replaying stages either. And yes we still get the boss rush room which I am not a big fan of but other than that most bosses were unique and had interesting patterns.
The weapon variety was a lot better than the previous games too.
