Awesome
I really like what you did with this series.
The first thing worth praising is the way you portrayed the characters. They're all the way they should be, just no terrible voice acting or unnecessary dialogue. Unlike Sega, you take them seriously. It's nice.
The fight scenes are worth recognition. My only reccomendation is not having the camera zoomed out so much. And not just with fight scenes either. You see, any lover of hand-to-hand melee combat such as myself would pay attention to the actual fighting. We love to see what moves they perform. But we can't quite see what's going on when the characters onscreen are smaller than a tooth. For all we know, there are no actual fighting sprites and you're taking a single regular sprite and bouncing them off each other as an excuse for a fight. You get what I'm saying?
I liked the music choices. Since I hadn't played many 21st century Sonic games, I don't know what the song was in the title screen, but it's awesome.
I can't wait for the third installment to this series, nice work and good luck Knuxrouge. I love you, bye! :3
