There are a lot of cool design decisions in this game that do a good job evolving the formula of Classic Mega Man, and I really respect it for being an 8-bit 2D platformer released by a AAA studio in 2008. That said, I think it goes a little too hard on the NES difficulty; the game's too in love with death spikes for me to consider it a personal favorite, even if I can see why so many other people do.
