The art and music is top notch, great story!
I think you could spend more resource on level design. I often feel lost and need to walk around without any purpose to find if there's a way I didn't check yet. The easier way to do this is put lantern into the right path and always let your player see it in some ways since it's a biggest attractive point and most rewarding stuff in the game. You can also put object with less reward, or some light to guide the player.
