So I started Metroid the other day, to really play it for the first time in my life.
It's hard! But I've been finding secrets all over the place.. Feel like such a badass.. That third area, I call it Crazy Town.. Really annoying area, and I'm working off a map I'm drawing as I go along. Can get confusing since many areas look identical.
But I just met Kraid and beat his ass! I had a crap ton of secret missile upgrades, but apparently after beating Kraid, I've got infinite missile storage, so, that's interesting..
I realize now that I have to beat Kraid and Ridley to enter that room near the start. I'm guessing Ridley is in the 2nd area I call 'alien bubble world', but I thought I had fully explored that area.. Hmm.. Actually there may be one red door I haven't checked out yet, behind a secret wall, so I'm not yet at the end of my rope..
Actually before I found the Kraid boss, I did some ninja level bomb jumping (for about 10 minutes straight) to jump into an area I'm sure I wasn't supposed to be in yet.. Came out a backside after some rooms, found a little Kraid enemy that died in a couple hits, and behind him was a bare empty room with a metal pillar in it. There was nothing in it, and I figured I was meant to come from that way, but after what I think, having fully explored that area, I'm not sure what it is now.. Maybe there's something there now that Kraid is dead.. Hmm..
