... It just gets better and better...
THis flash is of such a high calibur that I am beginning to consider calling Rigo "Kami-sama". Rigo, your skill of Flash animation is so nigh-godly that this deserves to be in the Top 50!
It is my opinion that this Flash is mainly understood if everyone watched Rigo's "Bass's Revenge" series first.
Your music selections were appopriate. The MegaMan Zero song for the ending was probably the crowning song of them all, considering that it fit the atmosphere you created.
Time for the easily understood crap:
"w00t! All my 5s r belong to this!"
... if this is your final sprite series, I'm gonna cry and then start slaving over my own sprite films... *sniff sniff*
