Ogmo Editor
What it is
OGMO Editor is a free, open-source, project-oriented level editor for indie game developers. Project data flows into level files that are accessible from the main window. Tile layers let users build levels from a tileset, while decal layers place images that can be scaled and rotated for decoration. Entity layers support complex game objects, and grid layers add metadata to levels. Edited levels are saved as JSON files, allowing authored tiles, decals, and entities to be parsed by other tools. OGMO Editor runs on Linux, macOS, and Windows and includes tilemap tools and entity placement. It is free for personal and commercial projects under the MIT license. An online manual explains the workflow in detail. The download page also provides community discussion topics and a changelog. The website credits Maddy Thorson and friends as the creators.
