Hi Anthony, appreciate your input a lot!
There already is an option to change languages in the main menu though! The default language of the game is in Spanish because we are from Buenos Aires, but when you start up the game and the main menu pops, the third option is "Lenguaje". If you click on it, the game will switch from Spanish to English. You won't have to change the language every time you start the game because once you save your game's progress in English, it will load the state in English (even though every time you open the game, the default language will be Spanish).
Hope you enjoy the game, any other feedback will be highly appreciated!
