Hi I tried your game. Couple of things that you could optimize:
Either give the options to skip the intro scene or fix the sound. Couldn't fix the sound until I got into the menu it was loud. The grey menu on grey background is hard to read. The scaling of the keyboard settings are hard to read. Space is not translated is it really called "Barra De Espacos"? :D Sound like a cool username kihi. In game I couldn't jump and the Duck wasn't also not working correctly.
So I doesn't work for me :(.
