Nice, but please sound off !!!!

Please insert a button with which you can turn off the sound !!!! The menu is limited to repeat, stop and continue playing. The puzzle is comparing its idea most likely with the known Formenpuzzlenzu: objects need to be drawn in a black form, surely nice for the little ones gaaaaanz. The pictures are pretty and appropriate for children
If you turn off the sound and effects, or at least could adjust quieter within the app, then there would be one more point!
