Hi Eduardo — just emailed you. I've set up a Google Sheet for the PT-BR strings (around 90 short ones, English | Chinese | blank column for you). Placeholders like {n} and {time} are marked in the notes.
I'll credit you as "Brazilian Portuguese Localization by Eduardo Vilar" on the itch.io page and in-game, with links to your ProZ and your site.
We're still in the Out of the Drawer Jam voting period, so build uploads are locked for now. As soon as that wraps, I'll add PT-BR alongside EN/ZH and send you the build link.
Take your time — ping me here or by email if anything's unclear.
