The first part of chapter 1 was really great! Your production and vfx/sfx are superb as in the prologue. Was particularly impressed by the cinematic scenes at the start of chapter 1 (the song was an unexpected but nice addition) and at the end of current content. Your scene composition and mood setting are great in general, too.
The sex scene with Vilnera was nicely written and animated. You're honestly making the best portrayals of energy drain I've seen anywhere.
In terms of story, I didn't at all expect the ship sinking and 'deaths' of Veara/Richard/Wade. Veara certainly isn't dead, but not entirely sure whether Wade and Richard are. They're interesting characters, but also not too developed, so it wouldn't necessarily be a waste to kill them off and it would help sell the impact. Separately, I really like the pairing of MC and Aziela, they have an interesting dynamic.
And, speaking of Veara, those nightmares are properly creepy - really well done with those. Wondering if they're just a product of the MC's fears or there's actually some weird psychic thing going on. It'd be an odd break of character for Veara, but my wild speculation is that she survived by energy draining someone, which could have had a strong psychological impact on her. Fits in with the corruption angle I was wondering about/hoping for from the prologue, though I don't know if you're going that direction.
As a last point on story, my current theory is that the MC's mom was a succubus, in particular one related to Veara so she and MC actually are related. Regardless of whether it's true, no idea if that's even possible within your lore lol.
Minor points of criticism: the MC is pretty dumb/oblivious/childish and there seemed to be fewer options to dictate his tone/responses to people in this update. Really, the first point isn't criticism, since those traits are kind of necessary to be the protag of a succubus femdom energy drain game. The second point is more relevant and exacerbates the first issue. Would have been nice to have the option to choose at least the tone of my responses to Aziela/Jason/Alara. For flavor, even if there's no relationship points or anything to be gained/lost. But these are both pretty minor items.
Overall, this is probably my most anticipated game right now, really looking forward to the next updates.
