Wuzgood pearman, This game was phenomenal. The sound design, graphics, and animation quality was outstanding. The storytelling and the plot is original too. After putting off the game for a bit (Js finished ver 0.3.5) I am now in doubt whether how I will be able to use my saved data on the older version in the updated version. I play on mobile btw. Much love!
