I have been using this tool and I am liking it so far, but I want to make a top down 2d open world, something that would have different regions, generated plants, trees, etc. Like all the stuff can you find in minecraft. I am wondering what would be the best way to generate a 2d world like that using this tool? Would I just draw my tiles? I am not sure how I tell the system when to make a it should place a desert or sea, or when it should place some dungeons. How would I use the paclage to make an randomly generated open world?

I think you could probably do a pass just generating the different "zones". You could even do this using WFC or some other procgen method. Then for each zone, use WFC to populate the zone with it's specific tiles etc. Just a thought.
