I don't think it'll be in either (registry, ini, cfg, etc). As it uses Unity, the controls are generally baked in. I think you can hex edit a value in Assembly-CSharp.dll, but I'm having issues finding the correct location. I'll update this if I find anything.
edit: looks like SensitivityY needs to be changed from 15 to -15, poking around in the decompiled dll. still no idea how to actually make these changes in the dll and/or find the right hex values to tweak. see attached image.
edit2: found where it was in hex and changed it, unfortunately it didn't change anything. i'll keep looking for other values to modify.
