how can I change the size of my font so it is still readable when placed on a small scene? all my pixel art is only around 32 pixels large, and I cannot figure out how to place readable text onto a scene this small. Is the only solution to increase the scale of my scenes and zoom out the camera?
You can create multiple dynamic text objects, at different sizes like small, medium, and large. Then when the game starts, swap out the font depending on the screen dimensions.
You could try rendering the text on a different canvas layer to have it in different scale or you could try rendering your game in a viewport so that it can be in different scale from the GUI.
