Update 2! (7m/24d/2020)
I added a new camera prefab that contains a render texture. I became aware that the base camera prefab I had included only supported the 64x64 resolution in 2d, but didn't support 3d projects. Hence the new prefab "Player Camera With Render Texture". This prefab adds the "Render Texture Camera Source" camera object that renders to a render texture. The main player cam object now only looks to render the "RenderTexture" layer. If you haven't added it to your project, then it will automatically add it when the camera prefabs are dragged into the scene.
I also lightly updated the message box as it seemed to have problems displaying while the camera was moving. This is now fixed.
Enjoy! And if you have any suggestions or find any bugs, let me know!
