World 5
Last no hit world I experienced on playthrough attempt #1.
5-1: Very straightforward. But 'tis a snowy level... awesome :)
5-2: First level with bullet bills and (if I am correct here) first instance of Buzzy Beetles as well!
5-3: A slightly trickier version of 1-3 with bullet bills. No biggie.
5-4: Sooo freaking many firebars* in this castle. The most challenging castle thus far. Still, it's pretty fun to play! Got through this one with no trouble as Fire Mario. Life is good.
World 6
I had six lives starting this level and two lives when I finished it :(
6-1: Night time! :) I wish I was playing the All Stars version of SMB, the backgrounds look pretty great. The trickiest variation of x-1 so far, but still easy. Killed Lakitu for my own entertainment.
6-2: I don't drink, but fun idea for a drinking game: Down a glass every time you see a pipe in this level! Pretty fun level, crapload of piranha plants. A preview of what's to come in SMB3's World 7.
6-3: 5-3 at night, with springs. I must admit, I almost fell to my death here! Thankfully, that was avoided.
6-4: Somehow I died four times on this level, the first time at Bowser. I got hit by a firebar earlier in the level then he got me with a hammer :( After a while I said screw it and ran through the level as tiny mario in about ten seconds... this did involve a good bit of luck, as I almost got hit by a hammer when I jumped for the axe!
Quick recap of World 7 to come, then this topic will be all caught up!
