this game is incredibly hard to figure out how to play, please make tutorial, only the text explaining how to play the game is not enough. Well I have to say good idea, good art, good sound effect. But the game is not balance out, it so hard to sustain out the money because of the RNG. the only was to make money is by placing the blue building and it not even give out enough money to sustain, considering there max building in one oil miner.
