Thanks for enjoying our game. I want both characters and endings to be meaningful, so feel free to interpret and decide as you see fit!
For text typing effect, I use Unity TextTyper open source package. ( link: https://github.com/redbluegames/unity-text-typer )
This package is awesome because it supports rich text tags and callback for character/text printed.
For the CRT TV effect, I use post-processing feature of URP (with Unity 6) by referring to this tutorial video.
The following post-processing effects were used: Bloom, Film Grain, Chromatic Aberration, Panini Projection, and Vignette.
However, I encountered a challenge: implementing a scanline effect using a custom Film Grain effect like the video doesn’t work well in WebGL. (This might be due to certain shaders not being supported in web browsers or a bug of Unity engine.) I experimented with various solutions, but the simplest and most efficient approach was to use multiple scanline sprites and animate each line to create the illusion of movement. ( You can check out the three scanline sprites from our repository here: https://github.com/devAdaid/SecretGrid/tree/main/Assets/Sprites/Scanlines )
Hope this helps!
