You might have noticed that the store page says that the only language in which this game is available is Brazilian Portuguese. Unfortunately, you read that right. No, this is not a database error, it is the naked truth. There is no English version currently available.
We do want to release an English version eventually, but right now, we can't. It would take a great amount of time and money to make it happen, because the whole game is dynamically sung-through like a musical, and we'd need native singers and lyricists with a good sense of comedic timing and all that jazz.
Therefore, we chose to make the Portuguese version available ASAP for the thousands of Brazilians that supported our local crowdfunding campaign and/or pre-ordered the game at Nuuvem (http://www.nuuvem.com.br/).
We are currently speaking to Valve and we plan to put a region lock on this game so that people who don't speak Portuguese won't buy this game by accident.
We are deeply sorry for all the confusion this might have caused, and we hope we'll be able to give this game the top-notch English localization we believe it deserves.
