Prototype a single playable level in Godot with input, UI, audio, save data, and the rendering style your game requires. Export it to the intended platforms and test on actual hardware, including a lower-powered device if one is in scope.
The editor experience is only part of engine choice. Check asset import, build reproducibility, debugging, and collaboration on scenes in version control. Keep the prototype narrow but complete enough to reveal performance and platform gaps before moving a large project.
