It could be better if Soinc had a little emotion to him because he looked like he had no animation and you just rotated his legs to look like he's running.

I saw this on Youtube before.

you used GTA Sanandreas

That was really weird! But I thought it was funny seeing Sonics legs move! XD

this would've been better on youtube.... but being a sonic fan I like it.... although the mod made sonic's legs reach his head when he runs 0_0
