I bought this game, and I enjoy it. Thoroughly. Anyone else play it? It's designed well and it's excess difficulty doesn't drag the game out in a bad way.
This was my first Mega Man game. A lot of the achievements are ungodly hard, like the one Jim said, and another one where you can't pick up more than 8 energy pellets, those 8 being from the boss rematches, and some energy pellets are in your way, and are hard to avoid
