Nice
Big fan of the games, great intro which you could tell a good amount of effort was put into, drawings weren't perfect but they were still very good. I will be sure to check out the episodes.
Reviews for "EarthBoundAnimatedOpening"
Good start
If you can keep this quality up for the whole series, then I reckon it could turn out to be pretty fantastic.
The main issue I have with this opening is that it's a bit long - if you plan to put it at the start of every episode, it'll probably piss people off. A way around that could be to either shorten it, or put a "skip" button in the corner.
I really wish you luck with this series - it looks like it could be a winner.
