Portions of the IDE are under different, less-restrictive open source licenses (BSD, MIT, and public domain).
Quadplay automatically adds asset and library licenses to your game's credits screen. You don't have to do any work to satisfy attribution clauses from open source or Creative Commons licenses.
All sounds, sprites, and games distributed with quadplay are Creative Commons licensed. The copyright and license on each of those is in a JSON file next to the asset.
