"Mega Man 2 for iPhone is obviously and unapologetically a complete cash-in, and so far removed from its original gameplay that it's not only virtually unplayable, but a completely different experience altogether. This feels less like a Capcom-published offering, and more like a thrown together hack made by a first-time hobby dev team. Skip it. "Over all score: 1.0/10 (Abysmal)
"There’s no other way to say it: Skip this game. I’m a huge Mega Man fan (one look at my IGN blog should tell the story) and would love nothing more than to see the series do well on any and every platform possible, but this is unquestionably a cash-in move, and could go down in history as the worst Mega Man offering ever. Jumping is completely broken, enemy spawners are random and inconsistent, the sound offering is chopped up and incomplete, and the game is virtually unplayable in its current control setup."
As I see it, this port is a great example as to why the iPhone simply cannot replace old fashioned button based portables; these types of games just can't be done without buttons.
