I played a little bit, but I got stuck on the first planet with the big mushrooms. maybe my tablet is too old to run this game. I was playing the english version, but some spanish texts still there, like in the notebook of the top right. "muestras para el laboratorio", "planeta zero", I can understand, because some words are the same in portuguese.
just for curiosity, did you use cocoon or intel xdk to make the APK? I was making some test APKs of my games using cocoon and the loading screen from C2 doesnt show. In your game the loading screen is visible.
