The game has a lot of potential, but it seems to suffer from its own ambition, as there's a lot of stuff but much of it seems unpolished. I'm looking forward to future improvements.
I have a lot of things I could suggest, but these are what I considered most urgent (1 and 4 involve spoilers, especially 1):
1. The lack of camera control in the "pirate world" is really frustrating. If you are going to stick with this weird point-and-click interface (personally, I would not, as it feels very jarring and awkward compared to the rest of the game---why can't you just use WASD to move and E to interact like on everything else?), you need to add some camera controls so that the player doesn't get stuck at the edge of a screen struggling to figure out how to click in order to move just to get a camera angle where they can see what's going on.
2. During sex scenes, the "H to hide UI" does not appear to work. This is frustrating, because the scenes are much more immersive with the UI hidden (especially the text instructions on the side), but you can't determine pleasure level or end the scene without the UI, so you have to mouse over the reveal button and then go to the end button when you want to finish. Definitely you need to fix that implementation, and I would also like a hotkey to finish the scene without revealing the UI.
3. The masturbation minigame is surprisingly good, and I'd like to see it replicated in the sex scenes (slower, so that the scene isn't forced to end immediately---honestly I'd slow down the masturbation too!). Instead of rewarding you with dexterity, it could reward you with more affection from the character you're having sex with. Controlling your pace so that you give enough pleasure to your partner but not going so fast you ejaculate immediately is, honestly, a big part of learning to be good at sex. (You can also make an option to turn it off for players who just want the fun part without the challenge.)
4. I just finished the current content for Ginger, and the scene where you show her your penis doesn't make sense. She comments that it's not "big like the movies", but the character is a complete shower: His penis is the same size flaccid and erect. So you need to either change that scene (maybe she comments on it not being hard, instead of being small?), or change the character model so that the flaccid penis is much smaller. Personally I'd prefer the latter, but I'm sure the former is easier to implement.
