A story-heavy adult VN about pirates? I am on board, captain. The premise is really interersting too, so I'm excited to see where things go.
Since you asked for feedback, there were a few issues I had with the game. First, the sex scene with Sabetha felt rushed. It was quick and impersonal, and currently feels like the MC lasts about 20 seconds. I'm playing this game to ESCAPE my reality, man. I think you should spend a bit longer on the actual penetration and having sex part. Maybe give the characters a few lines of dialogue during that too. Even if it's just moaning and talking about how it feels or even where he's cumming, then showing that. It'll all help make it feel more exciting and less impersonal.
Also, PLEASE give your characters nipples that are actually modeled. Just using a picture of a nipple on flat skin does not look good. The default, unmodeled jpeg nipples feel like a hasty nude mod for a game. Even with a story focused game, half the reason we're playing is to see boobs, so it's not a good place to cut corners. There are a ton of options for putting 3d modeled nipples on girls in DAZ too. It also gives you more customization, besides boob size, to make the different LIs unique: long, short, innie, pierced, puffy (my personal favorite), tiny, pancake, whatever you want to do, just make the nipples modeled.
I also wasn't a big fan of the music in the game. I love the pirate, fantasy setting, but the music didn't lend itself towards selling that atmosphere. Especially the modern songs with lyrics in them. I don't like having music with lyrics in VNs anyway, as listening to lyrics while I'm reading a story is distracting and pulls me out of the story. I ended up having to mute the music. I don't think I'm alone in feeling that way either, since 90% of VNs just use lyric-less background music.
Despite my gripes, I did think this was a promising start. I'm excited to learn more about Elva and what's going on with her. She's who I'm guessing I'll chose as my love interest, as so far, the other girls haven't quite been my cup of tea. Also, I really hope that redhead Laura on the other pirate ship is a LI as well. I'm a sucker for gingers with freckles and she is cute as hell.
