Alright, it has been cleared and as of 10:25pm CST [this post] it's now officially up at
http://www.gamefaqs.com
And, I've been making some trial and error runs... I actually NEARLY got my groove on with some luck at one point... managed a laser gun in the second area on my first life.. and managed to move and groove quick enough to nab some soda and keep it going [As seen in my recording, though a life was lost there]... then I REALLY lucked out and managed to score a speed up and a dynamite set to really PWN the living bejeezus outta everything..
Then I got screwed over 3 areas later by bats
And as for the castle? There's quite a few of them

Metropolis is the one you really want to be aiming for though.
I believe this game can be beaten on 1 credit... but... it's going to require A LOT of luck... and precise movements once you make it to Metropolis [if you find food there, it's SLIGHTLY easier]... and even then.. you're gonna want to have those 3 aforementioned goodies with full life to do it.
The only major hard parts are Olmecs and Meso... Garr gives you some relief... [food].. and then managing to hold out long enough with a laser gun to make it to Bundra [final area] ... then... at least if you die.. you have 2 more attempts and a base weapon can do some good damage... heck... I can kill the Devil in 2 seconds with some luck
I think though... there's going to be some major leeching required to amass huge scores.. 50k for the final area.. bleh.. especially if you know how to cycle the game areas to your advantage [food, food and laser guns if you die]

-Who think's it's time to take a run at Devil World and figure the mapping required for that one.. since the exits take you to different areas..
Just a gaming junkie looking for his next High Score fix.
