After some messing around the game eventually ended up continuously memory leaking, so I'm afraid I'll be unable to do much here. However, just based on the idea, I'll try rating it.
Balance: Not particularly well done, mobs feel way too hard in contrast with what you can do. I keep either getting killed on the first level before I can make more tea, or barely escape to the second level where I keep getting chased by bats anyway. Zombie drops still seem broken for me, dropping "orc viscera".
Uniqueness: Fairly standard RPG stuff. 3 stars from me- not great but not bad.
Fun: Had mostly great fun for the short time I was playing, although cutscenes seem to take up a bit too much of the time.
Theme: Well you mix potions. I guess that counts, although imo it's definitely not the most nuanced take on the theme.
Controls are a bit wacky- You should be able to press a key other than i/j to close inventory/journal.
Like I said before you can get past the bridge without doing anything with the pillar if you get pushed by an orc. Some of the journal entries also got corrupted and replaced with either "0" or simply empty strings periodically after respawn.
