Hey so I noticed you hired a voice actress! First off, I actually really appreciate that you went and took the time to hire someone to voice your game instead of either ripping assets or taking from free libraries. I know that sounds weird to say, but since you're running a patreon it's pretty cool that people adding an important part to it get paid for it. This is not always the case.
Secondly, I noticed this because I saw a video you put up with gameplay in it and heard the voice. But it wasn't always there, the...dorus, right? They only cried out sometimes when they were hit or died(since you're a big GGM fan I don't imagine you're gonna go outta your way to make non-lethal options). This makes sense, sure. You don't want people to get inundated with the voice and make it less exciting when it happens. Or, you don't have as many voice samples as you want yet so you're leaving gaps. If it's the second one disregard the rest of this post, keep on truckin', I think it's cool to make a creative effort out of things you find interesting, even if people might find them strange, especially since you're not hurting anyone. Just don't hurt yourself.
BUT if it's the first option, I want to disagree. In fact, I want to offer a counter argument. Having the sounds always play makes things more exciting for the player rather than making them monotonous. Aside from animations, sounds are the only feedback players get in a game. I could write a dissertation length fuckin' post about conditioning and limited interactions especially in action games, but I won't. Instead, I'll just say that sound is part of an almost Pavlovian process for these ryona games, and its constant presence as a reward for action is a big part of their appeal. You want to hear the VO, and that's part of the reward for landing shots, so you like to land shots, cause you want to hear the VO... you know. Even if it's one sample, the effect is the same. It's a direct change and reward for your game action, so it's satisfying.
I have evidence of this. You're a GGM fan so you might be aware of the Vorzen project already, so if you are... that's my evidence. If you're not, here's two links that might intermittently be dead:

A long time ago, a dude made little sprite based ryona games. There's two top down shooters where the sprites are very small, and there's only one sound sample for each enemy as they die. But rather than being monotonous, this is a core part of the experience. It's an auditory clue you're doing well, and one that you want to hear. It never gets old.
So don't be afraid to make the dorus moan a lot. People will like it.
