Hi qubodup. I'm Shaun, one of the co-creators of Concrete Jungle. Just wondering, are you asking if collaborators on this project are free to use their work on projects other than Concrete Jungle?

Our stance on this issue is that we will give credit and ownership of all work to those who created drawings, music or code for any game we work on. However, we would ask that a character, scene or music piece not be used as is on another project.

We'd be happy for artists to alter work and use on another project, as they are the owner, but we'd rather not get into the issue of copyright with other game developers if one piece of work was used in two different projects.

Hope that answers your question.
