Your game gave me a bit of FTL vibes! That's good!
Gameplay. While it's nice to be reminded of FTL, your game could give more feedback to the player. After I chose the class for example. Did it add more options for events ? I think so- I chose engineer, and my options felt technical, but I'm not 100% sure :)
Creativity. It would be nice if you added a bit more to the gameplay. Some personal touch, something that would turn heads a bit.
Audio + Graphics. They fit the atmosphere and are readable, so that's good. It may be nitpicking on my part, but I'd prefer if the ship flight and event illustrations had more similar style.
Theme. More "star" less "gazing" :) Just kidding, I get your interpretation of the theme. It would be cool, if you incorporated the stars into the gameplay more (maybe as a navigation tool).
