I wasnt too sure on where to go or what to do most of the time, but the atmosphere felt really well-crafted and I got the gist of the story. Really liked the art and usage of color, it gave everything a very surreal and magical atmosphere, and the areas felt very distinct. The character animations and drawings of the gods (?) had a lot of personality too.
I would agree with the other comments so far, I would recommend adding more "guidance" for the player, to know where to go next. And i also got stuck on the left side in the mortal realm as well lol.
Nevertheless, I could really feel your passion and how much effort and energy you put into this game, and its really inspiring seeing games about different cultures and mythologies! Keep at it, and well done on this one!
