I like that the game actually plays like a game, instead of an interactive movie. I managed to complete everything, and found myself wishing it was longer. So you're off to a great start!
I was having a lot of trouble with the framerate on my older machine when there were 5+ enemies on the screen, but lowering the quality (you should add a key for that, since it doesn't seem to be an option in the menu) seemed to help.
I did notice one bug, where if you die during a three-some with the whip-boss and one of the pirates, and then continued, the boss would become invisible and you couldn't interact with her. At least, that's what I assume was happening, since I kept getting hit for damage. I managed to leave the room and reset it by letting her slowly hit me out the door (which I guess is another bug).
I also had the action keys start vanishing for me during one playthrough.
Anyway, again, great game! I liked all the little touches in the story.
Also, if anyone is struggling to beat it, or wants to see all the different positions:
