Have I obtained everything in the demo? I have gone through the first level about 3 more times afterwards and found nothing else.
I must say, the sheer amount of animations for different situations present in this game is quite amazing. It's like every run I did, I discovered a new sex animation from the monsters. Only thing I would say could be improved is that the red goblins could appear red in the animations instead of green... and maybe also a Gallery option down in the future.
