Screen effect question

[BendyBread]

Are you saying the entire screen goes red, or are you talking about the red blobs of goo that appear through out the game? Because if it's the latter, that's supposed to be the physical manifestation of the shadow/just something to paint your pants brown as you put it

Personally I think its the latter, because I remember finishing the machine room and then the walls shaking and the shadow manifesting everywhere. T'was scary. :C
