So all of the things i said about the demo still stand except for the fact that in the full game, things are even better.
There are still some things that I find stupid though:
You can shoot the guy with the welrod pistol and they will just stand there and take it while you load the next shot.
Enemies will somehow know exactly where you are whenever you shoot.
At some points you can walk past an enemy without him even noticing you.
A cool thing that wasn't in the demo is the fact that loud noises can mask your sound. A little indicator pops up on the top of your screen when there's a loud noise.
Despite those flaws, I still love this game and know that I will have
multiple playthroughs as I try different ways of completing levels.
