Hey, thanks for asking!
An English translation is on the way, if everything goes well it should be done by May 1st. We should probably add that disclaimer to the page, that was a slip on our part.
By May first the game will have lost its initial favour with the search algorithm. It would be beneficial to have a translation sooner.
If you give us a list of all the Portuguese dialogue in the game, we could put it into Google Translate then clean it up ourselves for you. And if actually adding that text into the game is what would take so much time, for now you could make a devlog post showing the list of translated text.
But otherwise, you should consider uploading versions of your games that are playable in the browser itself. It massively increases the likelihood of your game being played, as many users would rather play a game in the browser than have to download one.
Not sure where these downvotes are coming from. Translating the game while it is still fresh in the search algorithm is objectively beneficial for its release, as is making it available in the browser; a highly sought after venue.
