Depends on what you're looking for tbh. If you're looking for a serious NTR, or serious storylines in general, then no, this dev doesn't have anything of that sort. Acerola is entirely focused on comedic stories and lighthearted smut and rape that's not treated seriously, so on and so forth. I mean, they have a scene in this game where a guy
literally trips and falls with his dick into Monica's pussy... That should tell you everything about what kind of game this is.
Every girl is a slut, or waiting to become a slut, every man is a horndog (the MC isn't really an exception here, it's just that his main kink is voyeurism)... In some ways, you could call the settings in Acerola games as "casual sex worlds" where stuff is treated seriously only when the seriousness is convenient in some fashion.
The games are also designed by default to mix and match event-lines, so the variety comes from that, rather than from any single line of events. Well, that and outfits along with situations, since context and all that matters too.
Sex stats do tend to be a tad useless in the so called NTR games, they have a bit more utility in the cum collecting games where the girls have sex skills that they can use one enemies and development level influences the effectiveness of those skills to an extent.
I can't comment on the voices, for a variety of reasons, I play these sorts of things muted, so I dunno what's what. I'm not sure if the version here is the latest version or not tho.
