I rarely post on this site, but it's such a waste to not praise this game. I have played a lot of H-games in my life but this has been my top 1 for a very long time, I've never seen such a game that has this much quality of animation.
The VA is pretty ok it's looped here and there, there are variations when the MC is getting her mouth full of dicks or just plain getting fucked, and exhausted.
Sound design is great, sounds crisp and satisfying.
As for Gameplay mechanic I don't really see the benefit of using the magic book weapons other than seeing the cool particle effects and having variety in weapons, you could always just use the sword and gets the job done much easier other than that everything is good. Bosses are so much fun to fight, the amount of content right now is pretty huge, you could try it for yourself.
The Menu when you equip things is kinda buggy, you can't exit out of the in-game menu when you equip things eg. rings, weapons, Ideas (currency).
Animation though... I don't know what to say to you man this is too good, it's just amazing, hottest scenes I have ever seen.
You could play this in a toaster or a Samsung fridge, it plays really fine on anything, except for that one level though the one on the violet slimes, and skeleton level for some reason it lags there.
Story is not done yet there are some small talks and event here and there.
In conclusion for what it is in this current version it's a great game that has a lot of work to be done, I would consider this to have potential to be a triple-A hentai game. truly a hidden gem I don't see enough people talking about this, this is what happens IF Asanagi directed a game.
10/10 would erase my memories just to feel and experience it all again.
