I have to be sincere I don't know what to say about this game, but four will try my best to ´say what I think in a way that makes sense.
First, I have FPS drops from 60 to 55 at times, and I'm on a GTX980 so that should not be a problem also if I use special senses mode and turn then the fps drops down to 7 FPS which is bad. I also had a glitch when I enter the second Snow Leopard den. It disappeared right when I enter it, and there was only a black ball where the cub sound was coming from. I hate the controls even when using a controller I need to map my keys and turn op and down for the sensitive on the controller and mouse. I also have a delay when using the mouse not much, but enough to I could see it. Also, the key mapping for the keyboard is fuck there just put on random like Q left, D right, Z is forward, S is back, C is crouch, A is special senses, and E is smell how does that make sense. Typical you use WASD as walk and ZXC or QER as the other keys Overall, I would not give this demo over 4 not even with all the other good stuff in the game.
