Two updates I’ve made.
I forgot to add that the “Game Camera” needs a “Pixel Perfect Camera” component as well. This component needs to have a pixel per unit size of 6 and a resolution of 64x64
The second thing is that the “Render Camera” needs to have its “Audio Listener” component removed.
Both of these are now in the guide, but if you used the guide the first or second day of the compo then you are probably missing those steps.
