Ahaha, I got glitched in the water level. Where you find the console game, I went through the wall, I am now swimming in the walls.
(By the way, playing on hard. I never played the other difficulties so I don't know what the difference is. All I know is that I die fast and health goes up slowly when I get fish.)
Edit: Glitch made me have to restart level, I can't get back into the playing area.
