i got super excited about the insanity meter (recalling fond memories of head pops and volume tinkers etc from Sanity's Requiem) but when you're at "..." level of insanity, it's rather disappointing. you stumble a lot, the screen bulges/wavers, and occasionally you get roaches crawling across the screen.
and there's no way to know what level of health you're at without entering/exiting the main menu :x
and there's no map system (and most of the halls/rooms look the same) and i am reaaally bad with directions ... so i get lost a lot and just end up burning through more oil
running from pissy monsters is annoying. like the first time I went "OH GOD OH GOD OH G" but after that I sort of stopped caring!!!
your "eyes" realistically adjust to the lighting--which is very neat. but if you are in a sprint through lit areas into dark ones, you're basically forced to grope around in pitch blackness to find narrow doors and halls. so then you never really want to use tinderboxes, but the oil runs out super fast on your lantern. but then being in the dark lowers your sanity, which makes you slower (i.e. monsterfood).
and every monster takes you out in 1-2 hits, and you can't really defend yourself, and they run sliiiightly faster than you so your only hope is to get to a loading screen so they stop following you.
you can hide, but then you can never quite tell if they're gone while hiding. and sometimes hiding places are hard to come by. you mostly have to resort to locking yourself in armoires or ducking behind crates, but sometimes that's just not possible. i guess that adds to the tension, but then it's so hard to get away from the fuckers when you're nowhere near a zone.
so it plays a lot like metal gear solid, if you are trying to get the achievement of never alerting a guard (and if you do, it's basically a reload). except in
this case, snake is a bumbling tool, can't go prone, and has no radar.
and also: OK I GET IT I AM IN A GREY STONE CASTLE WITH RED FURNISHINGS AND RANDOM FLESH PILES THAT HURT ME FOR SOME REASON I DONT UNDERSTAND, SOMEONE PLEASE CHANGE THE SCENERY A LITTLE
