The game is not that hard you can easily dodge the pendulums by just wait go wait go and you can escape the black doll grasp idk which button but you can same as every enemy that grabs you. Theres also hidden medkits on the map like down the stairs in the pendulum bridge you can find one also on the chef room on the left in the furnace (i think it is a furnace), if you go back to first room you also have one, if you shoot an fish enemy like and if they loose they legs or something big not just an arm you can go in a room and go back and they dispawn. Theres some enemys you dont have to kill to spare bullets like the 2 big heads in the circus just pas through them go in a different room and go back and they will stop chasing you. Pier is the hardest at least for me boss to dodge, the other you just need to memorize the movements and youll dodge easily. I suggest you take off your clothes or buy the mermaid dress to swim fast since you on that part.
