Great vibes, love the occupied hands concept and the overall aesthetic!
I think some ambient music or sounds (beyond the rare fire crackle) would have gone hardddd. The tension is already pretty ripe, but sometimes I'd have no clue I was anywhere near the monster and it'd just be too dark to tell. The light in general was brutal, always trying to juggle a light source means that actually gathering potion ingredients one at a time was really difficult.
There's also a issue where when I press buttons on the cauldron while holding a spell i end up wasting the spell, that was a bit sad.
Overall cool game!
