I like the game and how its coming along, but do you really thing a fulltime noise shader is "playable" on the long run?
I think its very distracting and creating some gfx issues (as bupaje mentioned the flattening of the screen) and a unpleasent distruction of the eyes.

Its like watching old tv shows on old tvs...this can be very anoying. To be honest i am a little bit afraid of that feature. I would recommend to make a turn on and off option for this one.

cheers
