I do the move by tapping A and then B in quick succession rather than simultaneously, just like in TMNT2. I have my index and middle fingers on the buttons when I do it.
I don't know if I can do much better. I can't hit enough of the electrified bots and jumpers in 2-1 and I take a lot of damage trying. Gaia's score is insane.
I do hope that we get to play all of Gyruss and Adventure Island, or at least as far as we can get, even though they're long. I think they're worth it. Making AI be a one life contest should cut down on run length for a lot of players anyway.
For Kickle we could use a password to start at a later world like with Burai Fighter. I wouldn't actually mind that at all
I have beaten TMNT3 but I haven't gone back to it.
TMNT2 is shorter and IMO plays at a better pace because you can quickly kill most enemies in one hit with your special attack. That's why I prefer TMNT2 even though both are good.
