Howdy!
As a game designer myself, I understand that balancing is one of the most difficult things to do in game development. But the right balance is often more important than graphics or cool features.
But first, I want to express my great admiration for the balance of weapons and armor. The developers managed to create a system in which it is practically impossible to create an invulnerable ship that could take out everyone and everything without getting damaged. It is very good! Congratulations!
There are several critical points that I drew attention to. They ruin the entire gameplay:
First, stations are very vulnerable. The first quests to save the stations become just a fairy tale. All you have to do is do nothing. It is enough to wait until the pirates blow up the station and all the resources are yours! If until this moment the economy of the game seemed balanced to me and it made sense to farm resources, then right after the first station I realized where my eldorado was! I just simply got a million money at the 5th level of reputation. After that, any farm became meaningless.
Secondly, the railgun is a damned unbalanced thing. Before I started building ships with these weapons, when moving to a new level of reputation, I faced new opponents and I had to change my ship to fit the new realities. It was exciting and cool! But as soon as I built a railgun with a range greater than that of all possible opponents, then I became immortal. Now my whole tactic is to stay at a safe distance from the opponents and shoot them without taking damage in return.
Thirdly, mining on asteroids and crafting in factories for something other than bullets and rockets again does not make sense. This is partly due to problem number one, and partly due to the extremely low price of resources such as steel and the extremely high chance of such resources dropping into gold wire and its high price.
