Hiya, thank you very much for your kind offer! Also, I really hope you enjoyed the game so far, and that the English speaking audience can enjoy it as well.
I don't see any problems with you taking on the translation task, but I'd ask you to PM me to further discuss the details. You can privately contact me in my Facebook page:

Or even leave there your personal e-mail if you prefer.
See you!
