Great movie, it captures perfectly the spirit of that stupid cave that made me so angry back when I was a kid (it took me a million years to get past it the first time because I didn't have flash, like you).
I love how you used the original sounds with your animation, and the "scary" touch was nice too.
And I have a few suggestions for other games you might make an animation for, excluding more Pokemon, which would be nice as well: AC Revelations, Batman Arkham City, the Uncharted series, God of War series, Dungeon Defenders, TF2, L4D2..okay, I think they're enough.
I can't wait for your next animation!
