Hello there Leonardo,
I am making a Bullet Hell game and I too have been wanting to make my games more accessible. If you're interested, please contact me on Discord at nichathangaming
The whole UI system in my game has been made with that in mind and I'm compiling JSON scripts which will have all of the words and descriptions in arrays organized by language.
My game is far from finished but if you're interested in doing some English to Portuguese as more of it is finished, that'd be great.
