It's pretty good! Some of Dan's moves are a little more powerful than others just because it seems like the AI doesn't know how to deal with them very well and can get stunlocked for a while - but it's pretty responsive. Not super responsive, but more than enough to be playable.
Dialogue is pretty funny. 8 taunting Hibikis out of 10 so far, with the potential to become 9 or even 10.
