LDtk
Modern, lightweight and efficient 2D level editor
... the process of creating levels as smooth as possible. For every new tool out there, there is this moment when you need to write the importer for your fav engine. I’ve been there too: so LDtk offers a Super Simple Export option. And by “simple”, I mean it. Define some simple rules in a visual editor and let LDtk do the boring part of the skinning job for you. Choose your world layout among “Grid-vania”, “linear”, or “free” and reorganize all your levels using plain old simple drag-n-drop.
