That would be nice. I'm a physical Buyer, too.
I may look into some method of providing the German language ROM at least for physical buyers in the near future, but the localization process was not free, and did take time, so the $6.66 download fee helps me recoup those costs while also gauging how much interest there is in German versions of future installments to begin with.
Love you all, and hope that's not unreasonable.
