Star tycoon

You have a long way to go on the path of a budding star tycoon. You start by having a small spaceship to collect ore, a miner. When you accumulate enough money, you can upgrade your production facilities to level 20 and buy new ships, asteroids, and even entire planets. There are 5 types of property available in the game. The higher the level of the property, the higher the income and the cost of their improvement. Your task is to buy up all available property and upgrade it to the maximum level 20.
