Liked the game and it seems by the name of the downloaded file that you intend to work on it so here is my review: First and foremost I like to say that I really like the concept of the game.
The combat: this is my biggest problem, it is almost impossible to hit the enemy ships. The asteroids and debris killed more ships than I ever did. I think this can easily be solved by increasing the fire-rate and speed of the projectiles. I would also increase the number of enemies while decreasing their fire rate. It will give the play much more to do and will be more fun.
Trade system: Pretty basic but a good starting point. Liked having to decide between the price i could sell it at and the distance I could travel. But think about maybe adding a shield that can take just 1 hit to give people a bit more leeway.
Great game and I want to see it more developed.
Note: the music resets when you go from the buying menu to the path selection menu. Its kinda annoying. a way of returning to the buying menu from the path selection would also be great.
