This version has a big bug with the game difficulty, as people have already written above, but I couldn't figure out what the matter was.
Firstly, the difficulty doesn't change at the start of a new game, no matter which one you choose, you will always start on "normal" difficulty.
Secondly, after you close the game and open it again, and load the save, your difficulty settings will reset to "normal" again, which is very difficult to earn money on and requires a lot of grinding
Therefore, after each new launch of the game and loading the save, you need to go to options-difficulty and select the one you need or configure manually. These settings will be saved until you exit the game.
