You guys can avoid the scat and pee if you try. I've never been forced into it.
Also here is a list of cheats you can type in a text box when you click "pagedown" on the keyboard.
If you don't see a text box your resolution is too small, I think you have to be in 1920x1080. Windowed does not show the cheat dialogue box apparently. So try the highest resolutions you can and see if any of them work for you.
By the way, for everyone struggling with the graphics, there is a an options menu. Change the language to English and it will make much more sense.
I went from 5fps to 30fps with a couple changes.
