I really loved this game. Everything was good overall. But! It would have been nice that the game might have been a little longer. It would also have been nice if the better ores were tougher to get so that the player could have a certain feeling of achievement when getting deeper and earning better stuff. It would also have been cool if there were more ores and if the map was deeper, and if the COre were a LOT harder to get. But all in all, great game, great gameplay.
