I think the currrent implementation of voice acting is good, just having I guess "key" scenes voiced. I was actually looking forward to the voiced lines while playing. I think it's fine to have fun moments to be voice acted, doesn't all need to be serious shit but occasionly the conversation would be as mundane as "Do you sit or stand when you piss" and that line would be voiced for some reason. It doesn't need to be removed but just something to think about in the future.
The only other thing i could mention was the quality of the some voices which isn't really a big deal. You're a indie dev not expecting s teir shit, I get it. Don't get me wrong, I actually like some of the acting but I won't name names since I'd feel like a asshole for being a snob about it.
