Simplified, we own the art and music, the developer owns all the code. We get a license to the code and can publish it across multiple platforms, we owe the developer their share no matter what platform their game ends up on. The developer gets a license for our art only valid if published through us. So if the game is ported by us to Android, we still take royalties.

The developer can strip out all of our assets and republish on any platform without giving us a rev share if they want.
