Uhhh......
No offense but, nothing made me laugh, I got bored after 1/4 of the flash, but I kept on watching, I didn't get any of the jokes, except the fire in the Lava Reef bit, which wasn't that funny, why is Sonic bigger than Eggman? why is METAL Sonic in Sandopolis? Sonic is meant to dash THROUGH the meteors, but the animation is ok, so, what could you do to make it better?
A. Try to make the things make more logical sense
B. We have seen Sonic crash into things and have things crash into him so many times, it's not funny anymore, try something else, like getting squished atleast.
C. Don't mix different styles, you should only use S3NK if you're going to use Genesis, if not another style, if you use another style, like Sonic 2 sprites, don't use sprites from any other game, unless they are level maps and items, if the sheets don't have the sprites you need, ask someone for help or make your own.
D. Try and put in more action, better jokes and some SFX.
Sorry, but I rate this 2 stars out of 10.
