This is a terrific review, though I do disagree with your assessment of the Double Gear ability's usefulness. I found myself using it pretty heavily most of the way through nearly every stage, to dispose of enemies and take out turrets and outrun waves of lava and almost everything in between. That's a lot more use than any of the earned robot master abilities got from me in this or virtually any other Mega Man game, so I consider it a rousing success even if I liked some of the other aspects of the outing less than you did.

"What if everything you see is more than what you see--the person next to you is a warrior and the space that appears empty is a secret door to another world? What if something appears that shouldn't? You either dismiss it, or you accept that there is much more to the world than you think. Perhaps it really is a doorway, and if you choose to go inside, you'll find many unexpected things." - Shigeru Miyamoto on secret doors to another world
