Thanks a lot for this comment. I didn't expect that someone would like my game so much. I will try to fix bugs and add some new things (including a save system). Unfortunately I can't say how much time it will take me because of my busy schedule.
I guess the game will find its players, without the need to rush it. I saved it in the list I have for promising jam games to revisit later. It reminds me of Space Rangers, namely the resourse managing part of the game (or trading) and the design. I'm surprised your game has so few ratings.
