First of all, thanks to the Itch.io team for making the process of publishing a project so convenient. I appreciate how straightforward it is to release something here and get it seen by the world.

GDC might be fun but I'm glad it's not a must.

With that being said, I'd like to present Tilesetter, a tool designed to make tileset creation more convenient by auto-updating and auto-compositing tiles. Hopefully it suits other game developers.
It's not released yet, but you can pre-order it right now. Would be glad if it got a feature.
