I added some text for you to play with.
Changing the font size in the GenDefaultFont command changes the size of the font bitmap. This changes it's placement in the atlas. In this case the font is 32x32, but you could make it smaller without changing the atlas since a smaller size bitmap will still fit into the same atlas position without overlapping other tilesets.
const scoreText = GenText("0", font, 100, 100, 256, Align_Center)
' It's always best to size the font correctly
' in the GenDefaultFont instead of using the scale
' (When possible)
GenSetTextScale scoreText, .80
GenAddText scoreText, score_layer
