Post Processing

So this time I made a game about getting out of a flooding city.
I decided to use a script to detect when you fell below a point rather than hitting a trigger for falling out of the world, so you can die, just like shown at the end of the video (Yes, you are intended to fall through that final platform)
Also, I used post processing as I could, but it got to the point where it would crash for me every few minutes, likely just my computer
