Just started playing, loving the story so far. I noticed something you may want to alter in future updates. In the scene where you meet Kayn and Druk the sprite arrangement makes Druk look like he is the same height or shorter than Kayn. You may want to raise the height (Y position) at which Druk's sprite is displayed, or if needed make other characters lower so that they appear shorter in the frame.
I don't know if the sprite images are all drawn/saved to the same dimensions, but how tall everyone visually is on screen is something to watch out for and adjust in coding. Its not that big of a deal, just one of those continuity things to consider.
