Awesome shader! just what i needed for my horror project.
Is it true that the saturation and brightness shader are the same shader?
Thanks for playing! Original plan was to make multiple levels which all were based around 1 upgrade, a soundtrack and some more polish, but I ran out of time and it was either this or missing the deadline:)
If people enjoy it I probably release a post-jam version, in which is bigger and more to my original vision.
