Adequat.
Graphics were still crappy because there was still a lot of white in a lot of the sprites areas. I was still impressed, because right at the Metal Sonic and Sonic fight scene, I thought to myself, it should zoom in a bit, and it did! I think you got your inspiration from Alvin-Earthworm. So I give it a 3/5 and a 7/10.
Uhhh....
First off... Why didn't you just put your website in the website... thing... it's easier to click a link then to copy/paste/remove the spaces... just to let you know. Second... It seemed drawn out... like, you were just wasting time... The sounds were good, but it'd be nice to have them all the way through the Flash (this does make a difference) And... Go through the story faster, the sprites could be custom because they don't move that much... don't you think? Anyways, it wasn't that bad, good job, next time make it have a little more action, and try to make your own sprites... If you can.
Enjoyable
This was a big improvement over the last video. You had a few plot holes but I'm not going to be a dick about it. Although you could have had a much better "incineration" scene. Also you could've given tails a voice. All in all not bad actually good so you get 4/5 and 8/10. I hope you work on expanding it
