The art and animations are really nice. I like the vibe and the color scheme of the game a lot. After collecting all of the potions, I wasn't able to do anything with them, so there might be an issue there with the cauldron check if you have all potions or something, but other than that, I love the game.
If it was just me who wasn't able to figure out something in particular, that's my bad, you can tell me what I got wrong if the game is actually beatable.
