Not sure if this has been posted yet, buuuuttt...

The game has outsold its iOS counterpart. Fascinating...

Just ran through this game. Took me less than an hour, so yea, super short. But a cool little game nonetheless. I enjoyed the style and soundtrack and though there was nothing at all I hadn't seen before, I am a sucker for classic Mega Man gameplay.

I thought the stage length was a pretty good compromise from the modern "checkpoint every five steps" approach and the much less forgiving games of yesteryear. The game did seem to actually get easier as it went along, though. I think they might have thought the later mechanics would throw people for a loop, but like I said, I've seen it all before. Perhaps I should have played Hard mode.

Is the sequel meatier and does it add anything new?

@Jargon

The sequel is just as short but it does add a few new gameplay elements such as horseback riding and Star Fox-ish level segments. Also you have different characters to choose from right at the beginning but I'm unsure if they change the game in any way. It's a fun game if you enjoyed the first. I thought it was more enjoyable overall. It's hard to really go wrong with the low price of these games.

I got this a couple of weeks ago as part of the Nintendo Humble Bundle and just ran through it today.

I beat this in one sitting (with Clive, Normal) and thoroughly enjoyed it. I think I died 20 times total, probably took me around 45 minutes.

I'll be replaying this in the future. It was no Mega Man, Contra, or Castlevania, but it was enjoyable.

Definitely short with the breath but still enjoyable for that little moment. I hear Gunman Clive 2 sincerely expands on it? I dunno.

@DrFinkelstein

I might give that one a spin sometime soon since it's cheap and I enjoyed the first one well enough.
