+1 to what others have said, the audio in this game is awesome! I see why you might choose to boost some ship aspects over others depending on what event you encounter. Most times I was just clicking the green choice over the 'no effect' options. Perhaps you can consider having options that increase 1 aspect and also decrease another, a basic trade off system.
(nitpick) I encountered 1 bug where I decided to sneak past a monster. It extended my journey by 1 event, but a new event never spawned, I was stuck at the space right before the planet. Pretty minor issue though, good work!
