This is a sokobandroid-based product.The original android source code is available at https://code.google.com/p/sokobandroid
The actual Sokoban level files were created by David W.Skinner - See his site at http://users.bentonrea.com/~sasquatch/sokoban/
Since I'm bad at drawing, I took quite a lot of ready made graphics from around the web: The target location image is from the Desktop KSokoban game - See http://hem.passagen.se/awl/ksokoban/.
The launcher icon is from https://www.iconfinder.com/icons/61566/box_wooden_icon#size=512
The graphics for the movement buttons is from https://www.iconfinder.com/iconsets/sphericalcons. Many more are available there.
