I used Unity's Rendering Pipeline for near all of the effects. There are two cameras, one that renders the player's view directly to a 160×144 texture, and another camera that just renders a quad with a material containing that texture plus some other nodegroup trickery so that it maps brightness values to a 1×4 texture containing the current colors.
I was worried that would happen on someone's playthrough. I did try to fix it by increasing the chances you would find the key exponentially, but that still left the very slim possibility that you could check literally every box and it would be the very last one you checked. I can fix this tho in an update.
So far, I know the specified limitations are resolution and number of colors displayed at once. Is going outside what would be expected of the limitations of the GB allowed or does that go against the spirit of the jam? E.g., complex animations, simple 3D, etc.
