I am developing a 2D sidescroller game for mobile platforms and am trying to figure out the best licensing option for this situation: My desire is to make the game's source code open-source, but the content (maps, graphics, etc..) proprietary.
The open-source component I just wish to be able to show in a Github public repository to support my resume and perhaps benefit the gaming / mod community with a small and easy to work with engine. Cloning this repository would just give the uncompiled source code and documentation
The full-featured game (levels, sprites, scripts, etc..) I'd like to be able to publish for a fee on platforms like Google play store, without necessarily exposing the raw content.
I would appreciate any guidance, cheers
