Well...
There were some good things and some bad... The animation really didn't impress me... The same actions over and over and over and over (see how that get annoying)... I liked that you tried to do a free for all thing and the beginning caught me by suprise a little... the introduction was well animated and when Sonic transforms in the intro, that was cool... I feel if you had the sprites do different shit, then this would've gotten a seven... Nice attempt, but I'm not feelin' it...
