Yeah, being in Germany you do need a key :) . I'm not sure why Itch didn't give you one, I checked and there are plenty of available keys, but I sent you one the the email registered with your purchase XXXXXXrsel@gmail.com .
got the same issue (germany, no key)
I don't see any transactions for Strip Em in the past 60 days... Maybe get in touch with Itch.io support and see if your payment went through....
