Greetings, space travelers! I've spent about 12 hours straight in the game (all day), and I've come up with a few ideas for your review.
I'd also like to point out that I haven't figured out how to send Amy to the shower—perhaps this mechanic isn't available once the ship is repaired. Also, with Jenny, there's a scenario where the captain assigns her two penalty points and a future punishment, but there's no option for punishing Jenny.
My suggestions for the game (I welcome any feedback and am happy to answer any questions. I'm thrilled with your project):
Sex toys for Amy during her punishment. As a cosplayer, she wouldn't mind a collectible.
The ability to influence the appearance of the ghost girl in the captain's bed (for example, so that after touching her feet at the communal table, she always comes the next night).
Add the ability to purchase sauce for food.
Secretly add sauce to Amy's food so she gets dirty while eating and then has to wash up.
Add a temperature effect in the cargo hold on the girls' clothing—at elevated temperatures, they unbutton their clothes.
Add the ability for the captain to unlock the doors with the captain's master key. Let him pretend the door wasn't locked. The girls will think the ship's age is to blame.
