Why are demo and development versions sold at the same price?
They aren't. The demos are free.
All game versions are all in the same price field.
You can't even buy Ravager for PC on Itch.
You're posting an image from the patch notes, which indicates which files were updated, not which files are for sale.
@Mattrex is correct. On the main page, there are buttons labeled "Download" above all of the demos.
