Victory!

Bowser throws <i>ridiculous</i> numbers of hammers all at one time. 
Go me. 

That took an hour and a half. That's not a bad start. Over-all, I'd say that it's definitely worth a play-through if you haven't done so in a while. It's not quite as hard as I remember it being (or I've become a much better player). Bowser's castle is <i>very</i> hard, though. It's a maze, it's got jumping fish, a hammer brother, and you're timed. Plus, no power-ups. There are two power-ups the level before, but there are 8 hammer brothers there. All in all, a good game. 
A quick food break, and them it's on the next game.
