Unfortunately I don't speak any Polnish, so I can't thank you in your mother tongue (except by trying to use Google Translate or something like that where I can't control if what comes out actually means "thank you" or "I'd like to have my toaster buried between to bananas" or something like that ;) ) but I hope English does it as well and so I just say: Thank you very much for this game! I received and activated the key. I hope you have a great week!
