I really love this game, and specifically the atmosphere, while also hating it for how punishingly difficult it can be and how little info it gives you about what you need to be doing (turn the thermostat to an exact temperature in order to not fight the giant bull thing was totally wtf)
Its a game that i feel like if i could just sit down and literally memorize everything you must do, i would return to it and beat it over and over again to unlock all the high power weapons.
Im currently still in my first play through though and keep getting burned out when i realize i missed something and have no real way to go back and grab it and then a boss is punishing me for it. It gets really old pausing the game every 10 minutes to read the next section of an faq just to be sure im progressing correctly.
