I'm glad you enjoyed the game despite the technical details you want. If you're not familiar with our company and how we run things I will give you a little low down. We currently have 4 people within our company (SR7 (FT), myself (FT)
,Newman (PT), Locke (PT)) two of those people are developing a Newgrounds project, then will be working on another undecided project on another sales platform (steam, self sold, somewhere else). We are currently working on our development pipeline with other people and running small projects in order to flush out the process. If we ever get of Patreon, or diversify our income we need to have some really tight processes in place (let us be honest and say we started as amateurs and are working to become solid pro's). So the amount we take in per year goes to funding these endeavors, SR7 has always wanted to keep this project his own and it will stay that way till he moves over with our other team at a later date.
As for the voice acting, we don't see the juice being worth the squeeze right now, especially in the case of SU. When working on parody we need to be super careful as all it takes in one DMCA and it's lights out for us (we would still survive, but we wouldn't have the other projects running). Trying to add some voice acting just exposes us even more, that is a risk we will not take.
We haven't missed an update since we started in June 2015 think about that for a second. Not too many creators in the h-game scene (some were bigger than us, others not) can say over a 3 year period they have delivered a playable build month over month. This game wasn't supposed to be this big, but SR7's perverted mind got racing and he just creates what he wants, he still loves to do it every day. That is why this game is where it is today.
You are 100% correct with the voice acting in my opinion
We are running very close to what the fan's ask for and want (it is seen by metrics you do not have access to). If we were to look on some boards we will see hate, it's been that way since day one. Literally in 2015 a concept would get more love on /weg than our builds. In the end we are here for the long haul and will always operate that way. Progress is slow and so is the forward progress of our company. We operate smart with money and only do things that make sense, that is how you build loyalty. SR7 can sound like he is disinterested and I get that, but how can someone not care and still put out 33ish updates to this game. We listen and where we are today and how we do things is all based on community feed back.
