3 out of 5.
Has the potential to be much, much more; the visuals are fantastic, the music is decent, and the overall story is a little schlocky and rushed so far but entertaining enough. The sex scenes are actually pretty great- the focus on female pleasure actually makes the game feel erotic. I generally like the characters' personalities and their interactions, too. So what's the problem?
The writing. It's... not good. The prose, the grammar, the syntax; the dev's grasp of English is rough. It's entirely functional, but he doesn't understand past or present tenses (sometimes mixing them up in the middle of a sentence), he uses purple prose in situations that don't call for it, he mixes up words (he said "ravished", but I guarantee he meant "famished"), and he doesn't understand double negatives ("If I left, our money problems would never cease to disappear", meaning that the problems would never stop going away). There's a speedbump in almost every line that keeps me from enjoying the story. Write how people talk, dammit. Sure, people don't use 100% correct grammar when they speak, but they hardly ever make these kinds of mistakes, and they never sound this robotic.
EDIT: I want to add something- the more I think about it, the more I want to emphasize how bad the purple prose is. For those who don't know, "purple prose" is when the writer uses excessively flowery language, thinking it makes their writing look more impressive, intellectual or poetic, or simply in an effort to cover up the prose's faults. The dev is doing all those things here. The writing isn't nearly as smart as it thinks it is; lines like "Perhaps my naivety spoke a few decibels too loud" or "in this distance, every twitch of the muscle, every flutter of her eyelids played on the canvas of my corneas" aren't clever. They're pretentious and irritating. You're not painting a picture with your words- your scrawling with crayon. Pull back. Drop the excessive metaphors. Use more conversational prose; believable dialogue has more impact that overwrought glurge.
The dev desperately needs a competent English proofreader and editor to go over the game. Fix the dialogue, and you've got a real treat.
