Very good.
Those 3 months of work seemed to have paid off. Since you've delivered another great episode to add to this series. Nice to see the Wario bros make another appearance, since it feels like it's been 2 or 3 episodes since we've seen them. And to see Mecha Sonic kick almost everyone's ass.
Nice to see you using a lot of effects, like the blurring and camera angles, and whatnot. And having stuff going on in both the foreground and the background. I should have expected to see that over 9,000 thing coming sooner or later.
Little bits of humor here and there, which was a nice touch up. Good use of all the voice clips, and sound effects.
Overall, an exceptional job on another good episode. Can't wait to see what you will come up with for the next one.
