This looked promising! Unfortunately, it doesn't run well on my system and there weren't any settings I could launch to adjust, but what I got into looked lovely. Hopefully others with a better PC will come along and give it a shot, haha!
So apparently you can adjust the quality with a console command. It's really easy. Just start up the game and press the "~" button, then type "SCALABILITY 2" and hit "enter". That should lower the quality down. If that's not enough, you can try doing the same thing but changing the number to 1 or 0. Hopefully you can play it now! Let me know whether or not that works.
