I also wish Knockout City supported more communication options between players. Hopefully that's sorted out soon so I can stop having to remember that I set it somewhere between 50 and 55.
No matter what I do, my mouse sensitivity will always reset every time I launch the game. I have encountered a few recurring annoyances in my first few days. That sound used to haunt my dreams and now it has followed me into videogames. Bonus points to whoever captured the snappy, elastic "bonk" of a red rubber ball meeting a hard surface. Besides gauging a ball's distance by sight, the increasingly loud "whoosh" of the sphere barreling toward your face can be used to perfectly time a catch. Sound also plays a key role in timing catches. Every action, be it a hit, knockout, catch, collision, or special ball, has its own distinct sound that can be easily picked out among the chaotic soundscape of jazzy tunes. Sound design is carrying a lot of the weight here, too. The basic rules of dodgeball naturally create comeback scenarios where I'm repeatedly catching/throwing/catching/throwing until I'm the last one standing.
Even when I'm ganged up on in a 1v3, I have the opportunity to either dodge or catch every ball sent my way. Balance appears to be a major consideration for developer Velan Studios. Obviously there's depth here, but I'm impressed with how harmoniously Knockout City's mechanics gel together.
