OK, I did test on the first level out of proof of concept. I aim for about 90% speed and 10% trade offs, the trade offs only take up a few frames and not seconds, often I can do them without wasting any time given the nature of 2 players. Its fair to say that the levels will not be 90% turbo style punches and 10% team attacks. The fastest way to kill enemies when they appear on screen is with a team attack. Its preferable to have Blaze tossing Axel because she throws him at a lower projectile. When the characters are in a ball they can effectively KO all enemies. If they come out of there ball then the other player will need to apply a little bit of damage first in order to apply the finishing blow.
While the AI is very simple its not paticularly TAS friendly as enemies like to behave cautiously at first, often back off when agressvively approached, the best way is to leave a little distance between the edge of the screen will facing away, that way enemies will act tentative for a shorter period and make a mad dash on screen. I also show off a couple of glitches as well.
Incase your wondering why Axel kicks Blaze, that was strangely for manipulation purposes, it causes the guy to charge faster, if I throw any earlier the guy backs off agressively and doesn't get killed. Overall the level is about 7 seconds faster than the current run, it might not sound very impressive but it must be taken into consideration that there is an extra 20 enemies to kill and often they don't appear until you beat some of the eariler ones. The one thing I'm annoyed about is that I don't optimally do the turbo style punches the first couple of times, I autofired the B button and didn't do it properly like I do later on. Damage is taken like I just mentioned earlier on but only ever dealt by fellow team mates. Overall I'd say the level could be improved by 3-4 seconds. Anyway,
here is my first level at long last
