Thank you!
Cocky John is meant to be the Glass Joe of the game, the rest of the opponents require a TKO to beat and will have a much higher Stagger and HP threshold. The movement patterns also get faster and more complex with punch combos.
The varying volumes for the actors is the mature of getting the assets from so many different people, all that will be evened out in the final version.
Any advice for the NVDA thing? Did you play on Desktop or Windows?
