Wow! That was an experience, not only does it feel well put together and comprehensive, but I feel like that perfectly encapsulates the theme of the jam. I can definitely see some of the inspiration leaking through, notably Dome Keeper and if I'm not mistaken the character portraits remind me of Papers Please (excellent games as well). Now I know I say you can see the inspirations, but the system you ended up creating for this was not only unique, but a lot of fun to play. I'm a sucker for upgrade based games like Learn to Fly from back in the day, and that progression is tons of fun!
Couple of highlights: I really enjoy the flavor text from each individual character death, the fact that you can kind of "cheese" the mines to avoid early death, and the slow pan back to the ship forcing you to look at all your sacrificed crew feels perfectly in place for a game such as this.
Nice work! Will definitely be checking in on your other projects too! Keep it up!
