I just tested the game, it does not cost anything. What I get from this test (20min) is the discomfort caused by the graphics engine. it's dark, it looks like the colors are the black spectrum. I changed the nice gamma setting, at 0.5 the game is darker but there is no color, if you want colors it's dark. Too bad for me it's unbearable.
Please help. Thanks!
I didn't find the right solution from the Internet.
