I’ve worked in both Godot and React Native. I wouldn’t say you are eliminating any complexity.... You are just trading one UI system for another. UI by its nature is complex and requires a lot of “code”. In the Godot case you might be doing less coding in the “typing letters on a keyboard” way, but you still need to figure out the UI controls and fiddle with the settings in the properties panel until you get it juuuust right. The final product is still saved as code, in tscn scene files.
