Keeps getting better and better
I took a look in the flash portal, saw "Super Mario bros Z ep. 6" and got excited. It is extremely rare for me to do that, and after watching it, it made sense for me to get excited.
You really have put a new light on sprite fights. The amount of time it takes to get such placement done and to tween at an appropriate pace takes a great amount of skill. I still prefer making movies with drawings, but anyone who thinks sprites flashes such as this take to skill just really need to get off the internet.
Fight scenes were fantastic and mesmerizing. I loved Sonic's little fight scene. That's what I wished I would have done differently with Nazo Unleashed, to give regular Sonic more screen time to show off his speed. Shadow was pretty badass throughout too.
I'm glad you did not cut it off with Mecha Sonic charging the ball. That'd been a little cheap haha. And the story does not drag on either. I thought Mecha Sonic would have died this time around, but it looks like you could easily add another 2-3 episodes on with new content.
Overall, great fight scenes, nice cinematography, and a strong and very entertaining story. Perhaps I'll see Episode 7 around the time I submit my final part =P.
Oh, and loved the "over 9000" touch. I always wanted to use that lol. Now if you put in "I hope my body can take it" somewhere nicely, that'd be something. If you don't know what I am talking about, check youtube.
