Thank you! I didn't intend on making the demo project open source so it's messy, it doesn't have version control either. Maybe I can clean it up eventually and make it open source.
I've mainly used a `EditorScenePostImportPlugin` to swap the default Godot material with a custom PS1 style one on mesh import for that pixelation and vertex wobble effect.
Then I implemented a simple character controller and interaction system and that's pretty much it.
