Very nice, I love a nice farm game! The idea of having the farming day be restricted based on your battery life is very cool, and the fact that everything grows in realtime and you have to juggle different things to maximize your output is nice. Fun dialogue sound and graphics too. I think this could be expanded in a great way.
My only critique is that I wish you could skip just the current dialogue and have it move to the next line. I pressed space expecting that to happen and it skipped over the entire tutorial. Also having a quite button would be ideal for when you finish the game.
Great job!
