I finished the game. It's very good. Although.. I.. may, have used cheats, like a JSON editor, to speed up progress.
Right after you start the game, save as soon as you can and close the game. You can open the JSON save file with most text editors, I recommend Notepad++. Find where it says \"money\":\"100\" and change the number to something huge, like 1000000000000. Open the game again, load the modified save file, and you should have all the money you will ever need.
