Can you spot what's new? (Patreon)

Can you recognize a new addition to the fights (Other than the new characters)?

Answer below:

Okay actually many of the comments are correct. I forgot there were a lot of slight changes in addition to the one I'm referring to, so good job on everyone for catching those.

The feature I'm referring to is the head twisting when punched in the face. I didn't have this implemented before (don't know if anyone noticed) as I failed many times trying to. Today I managed to figure it out after some experimenting!
