I love it, very cute art and a fun vibe.
I was trying to look for hints as to what the other potions could be, I couldnt figure out anything that wasnt in the book :P maybe some hints in the item descriptions to nudge the player in the right direction?
I really liked the idea of the cauldron health affecting the risk, but it could have been harsher on the player, it didnt drop below 90% for me and I blew myself up a LOT
Overall its a really fun game, nice work!
