Cool concept, it reminds me of the code.org visual coding games. A couple suggestions, first, if you want the UI to scale into the smaller box, instead of needing players to go into fullscreen, you can use a canvas scaler component, and then second, I would have the commands on screen, or have a button to view them again, as it is easy to forget some of them, and then you have to restart to see them again. Other than those two things, great game!
