I’m currently working with the DLC team to get all of my content added there, but a lot is still missing. At the moment, it mostly includes Fantasy Dreamland and Rogue Adventure assets, and it’s not complete yet.
If you’d like to get the full set of tilesets, I recommend the world packs available on my itch page. If you’re looking for a better deal, the Mega Bundle would be a good option.
If you want everything along with lifetime updates, I recommend the All-Access Pass.
