9 and 10 are both very complicated. I think the design of these two works MUCH better in 9 than 10, at least with my limited experience of these games. They tightened and limited the move set for this one back to Mega Man 2 mode. It works, as the levels are designed around this idea, but playing all of the games in a row made this one stand out a lot less to me. It is definitely frustrating in parts, and I think that is an homage to 2 as well, which is alright with me. I was able to clear it without any major hang ups, and it was well designed, just doesn't come to mind when I think of the best games in this series, but that may change with more replays.
