Hi :)
I already have Godot-ready assets available here for free : https://store.godotengine.org/asset/gif/super-retro-world/
It comes with autotiles terrain (most of my autotiles actually). This is all I've got for Godot 👍
Once Godot will have paid assets available, I'll make a complete package on their store.
If you get some of my paid assets from itchio, you'll have to import it yourself on your Godot project.
Thank you for your consideration ❤️
