Do you mind adding an open source LICENCE file to your github repo? That is the #1 rule of Open Jam. Also did you use any other open source tools? Or could you add a Linux build? Right now you have 3/5 open source karma points:
You can get up to 5 karma points, and you are missing a possible 2 points, if you used any other open source tools, or if you can add a CC licence to your assets, or add a linux build all will get you +1 open source karma points each.
