This was a really interesting and serene game, I liked wandering around looking for planets with this atmospheric music playing in the background! Most of my critiques are already mentioned in other comments (i.e. lack of a map/background when moving in the darkness, not quite understanding the buy/sell resource system), but this kind of game where you act as a diplomat of sorts is really cool and has a ton of potential as a full-fledged game. I would love to see where this goes next, great job!
