Very good game overall, I am able to go through 3 gates but do not know how to proceed further. I like the AI setting most as well as the moving of the character which makes it neither too easy nor too hard to get rid of the enemy. Also, the manual as well as the automatic adjustment of the camera makes me able to play with the game without felling any bit of dizzy.
Some suggestions I would like to give is that I noticed that sometimes the guards are able to see me even though I am staying behind the wall. I would suggest make the light zone of the guard not penetrating any walls. In addition, I am not able to get through the whole game because I don't know how to proceed further when I went through the 3 gates. Maybe it will be better to give me hints.
