So I noticed that this topic hasn't got any posts in a while, so here's my feedback that's not already posted.
- Gizoid's fireball attack could use some sound effects
- Espio's tornado attack could be "overlapped" over Espio himself (Like how Sonic's Sonic wind overlaps Sonic, get what I'm sayin'?)
Well, that's all the feedback I have. And I also realized that you never got your Sonic Boom Amy sprites, lol.
