Good and Good
This flash was done very well. The premiss is a little worn, but the action more than made up for it. The sounds was synched nicely and the bgmusic was superb. The only markdown I have is that it is all done with sprites. Nice production.
As for Sonic losing, I don't see anything wrong with that. He's a runner not a fighter. And he's a hedgehog fighting robots with laser cannons. That is all.
