Sometimes staircases wil have a white like going across them usually just one.
Getting too close to a door or wall will make a black are near the top of it.
I dont know if this is a bug or meant to be in the game but if you attack and block right after there's no delay.
and another thing, I dont know if this is a bug or not but it makes thing a bit hard for leaning, everytime i press Y to lean and I let go of Y and the joystick so im still leaning and if I start to move he'll continue moving for a bit still in the leaning position, also the delay to lean left or right and to unlean seems a bit long.
Other then all that which is all minor to me It's a great game and I love it.
