Hello!
I'm Brazilian too and would love to help on the translation, also I honestly think that Brazilians would be very interested in playing this game in portuguese
I have a lot of experience in english as well as creating content on both languages and if this translation gets started I would help without a doubt.
Thus, I may not have tons of free time but I think I got just enough to help out a lot and if there is interest on it I'm already volunteering to help out, hit me whenever and we can do it
