I seem to have commented on a message, but I can't find it. To be on the safe side, I'll post it. I mean, I hope there are examples of maps that can be downloaded as a reference.

Somehow you ended up in a devlog and posted there.
There are TMX file included - for tiles. Just open them, you need to have the graphics file in the same folder or relink it in tiled itself so it gets loaded. Apart from that, it's pretty straight forwards 8x8px grid. In any program - hope that helps,

Hey there, you use the application "tiled". It's actually the "go to" for tilemaps. There is also a way to use tiled with godot, tho it depends on yxour programming, but you can also use them seperately. The application is free and can be found on itch too. I highly recommend using tiled for tilemaps and designing. The later maps can be exported and used via godot. I am not sure if it is supported natively, until know I usually programmed it into it.
