Spread Colors 3D

The game itself seems good and there's no ads as far as I've seen, but there's no text in the game whatsoever. When you start it up it's just a blank blue box at the bottom and after you finish a level it's just a round green button in the middle of the screen. It seems clear enough that you're supposed to press the buttons to continue, but I assume there's supposed to be something written at least somewhere in the game
