Ok, so I have a question regarding the password glitch that people use on runs of this game. Is that password really a glitch? Think about it for a second: The password literally translates to "Momoko", a common female name in Japan. So, what if that password was actually left in intentionally by one of the developers, as an easter egg/debug code? Maybe as a reference to one of the developer's relatives or something like that. It's a strange coincidence that a common Japanese name just so happens to let you skip levels.
I dunno, that's just an observation on my end. I don't know what you guys think about it.
Ok, so I made a TAS of this game using the password last night: http://tasvideos.org/userfiles/info/46211363890835690
Maybe someone can look into this further with BizHawk's tools or something?
