Congrat on your entry! The amount of feature is impressive! The gameloop is coherent and I got immersed into the game. The theme is very well respected!
I would make 2 suggestions better introduction on how to use the cauldron vs transmuting (crafting items throught your inventory) and give some rewards when the player kill an enemy (maybe some item, even useless ones)
With a little bit more polish I could see it on Steam :)
