Hi wormo! Thanks for playing, glad you liked it. Shame you got stuck, but thanks for letting me know! Did you try interacting with any of the letters of the sign?

The pixelated look is really easy to achieve in Unity with 2 cameras and a Render Texture: https://docs.unity3d.com/Manua...

Have a low-res Render Texture with Point filtering in your scene, set it as the target texture for the camera of the first person character. So the Render Texture will display what the first person camera is seeing in low-res glory. Then, simply have a Main Camera pointing at this Render Texture. I'm sure there's better ways of doing this (this method doesn't take the screen resolution into account in any way, for example), but it works.
