I think its a good effort but yeh I would set up the input keys differently so its more what people are used to. It had me thinking of the game Portal.

The inputs can be a bit messy but other than the respawn i though they were standard enough? I saw some games using the numpad to control the camera and the Q/E/R/F keys too, can't remember which one it was though to reference the name.
One thing that I'm definitely going to change will be to capture the mouse into the screen, and get the camera rotation from there for a better experience.
Thank you for the feedback! :D
Edit: If you could be a bit more specific about what you would change, that'd help me figuring a better solution when i reprogram the inputs.
What i have in mind is to remove Cinemachine's input controller, and make my own. Then for keyboard I'd make the camera snap to 90º turns, but for the mouse, to allow free camera spin using the mouse for camera horizontal movement, and the mouse wheel to zoom in/out.
Ok it wasn't the ball movement controls I didn't like it was the camera controls.
I'd treat it like a 3rd person combat camera with right mouse button allowing camera rotation and zoom in and out on the mouse wheel.
Maybe that is subjective but I think its better than Q E R etc keys, having to remember those keys for camera distracted me from the game.
