Sprite Fusion
An online tilemap editor with layers, collision, animated tiles, external tilesets, and exports for several engines.
Why use it
Level and art contributors can assemble platform or top-down maps without installation and hand prototype data to the game quickly.
Where it fits
Use art, animation, audio, levels, and narrative to make the game easy to read and its world convincing.
What to check
A browser workflow is not version control; test custom properties, very large maps, and target-engine import before committing.
