Please, decrease drone repair cost. Drone repair cost is so expensive that i can't earn money. For example, if you attack a mine protected by one Guardian, the cost of repairing the drone is 100, and the profit you can get from the mine is 50 or 25. This is the same when collecting spaceship debris. As a result, unless you have a lot of good luck, the more you play, the more you lose. This is a serious problem with the game balance, and i hope to fix it soon.
