This one's a good one.
Well, you mixed alotta sprite styles, most of them worked, fighting was pretty stylish, you use some sfx too many times, the interactivity had scene select and replay, and there were a few funny little jokes. Now onto what everybody loves: CRITICISM!
1. Did you have to give the Axem rangers Zero's HAIR? That = NO.
2. You need to keep the action flowing, this one was really similar to the second episode, the action was too late and not enough.
3. Add some new effects and sounds, the double wink thing before a strong move is REALLY old these days, and the "Emerald Get!" noise get's kinda annoying.
4. Put in more music!
5. I'm so angry! WHAT IS THAT MUSIC THAT PLAYS DURING THE FREE FOR ALL! I've seen it in SO MANY MOVIES, yet CANNOT FIND IT.
6. You ever get on AIM/MSN? If you ever get the chance, please, conversation = YAY.
7. I can understand if Sonic and Shadow are like Goku and Vegeta, but come on, Shadow is WAY too Vegeta. His sense of humor is like, nonexistant in this!
8. <Insert Complain About Axem Rangers Hair Here>
9. I like some of your sprite edits, but having all but ONE Yoshi a Snes sprite, and having the Chief Yoshi a Paper Mario sprite? I think you'll need to start sticking to a bit of a more consistant sprite style.
10. I know Luigi is a bit cowardly and more comical than most in the Mario series, but give him a LITTLE more splendor than that!

12. Shine get.
