Very well done for how much time you had to work on it! Definitely would be an awesome concept to further explore. Mechanically, the implementation is great and I'm sure would set you up for success if you ever plan to update the game! One really small suggestion I have is making the ship menu exitable by pressing tab. Whenever I tabbed into the menu, every time I attempted to press tab again to close it, and it felt unnatural to use the mouse to close out the window.
Nice work! :)
