This is a good start 🙂

I've made a branch based on your fork with further improvements to better match the existing visual style and code style: https://github.com/Calinou/godot-demo-projects/tree/platform_level_generation_godot_4
I still need to make some tweaks to it before it can be merged.

These visual improvements are much more intuitive. Can I help with any enhancements?

I can take it from here, but I won't be able to submit a PR soon as I'm busy with other tasks.
