Hi,
Thanks for the message! Great to hear the assets are useful in your game dev journey.
Regarding resources and tutorials, I don’t have any custom tutorials. But there are a few good ones on YouTube explaining how to setup and use tilesets/tilemaps, like for example this fairly short and simple one: https://www.youtube.com/watch?v=PDlwQM1AnYI
If you could send me an email to deadrevolvermusic@gmail.com, I’d also be happy to send you the demo Godot project with the tileset setup.
I hope this helps.
