DO NOT play the game in Hard Mode, it was not designed to be played without Health, unlike the original.
Sligs timings are WAY too fast in this remake, most sligs that notice you in the original have a small delay, usually enough to let you escape.
If they spot you in the remake you're pretty much dead in hard mode, absolutely no room for error, health gives you some lenience in normal mode.
I've beaten it, but I ruined my entire experience by playing it in hard mode, so that's cool I guess.
As for the game itself, it's an ok remake, only play it if you've beaten the original to see how different it feels, just remember to disable those godawful bloom and dirt lens post processing effects.
