There's no infinites from what it seems. There's this sorta system that cancels out infinites. Like, the dash cancels feel amazing. But, after 2 or 3 dash cancels the opponent flips out of the combo.
I am not sure what causes the flipping out though... At first I thought it was the proration by number of hits, so I tried doing dash cancels with just stronger moves, but then I noticed they were still flipping out with around the same number of dash cancels I did. So that's when I thought it was the number of dash cancels... But I've seen them flip out much earlier. Maybe it goes by damage proration or if it's the same normal/move in the chain.
Other stuff I've found is that you seem to be able to hit them while they are flipping... I am not sure if there is an air guard, but I have the opponent set to auto block in training mode, and I've been able to hit them during their flip every time, thus allowing me to continue the juggle.
Like with the blonde girl with the sword(I don't know their names!).. I was able to do 2a5b5c2c dash cancel 2a5b5c2c dc 2a5b5c (flips out) 623a 623a 623a while in the corner... then after the 3rd 623a I can't connect any more.. kinda how in 3rd strike you aren't able to juggle them anymore and nothing will connect.
And no, I am not shitting you... This game is fun, what's so hard to understand about that?
