I can tell a lot of work went into this.  That said, it's not playable.  A "next" button got stuck and I missed a bunch of dialogue.  Dumped ingredients in the fire until I figured out how to drop them on top the cauldron.  Brewed a potion for tavern guy but couldn't deliver.  It just disappeared when I dropped it on top of him and I didn't get paid.  Some animations showing what to do would help a lot.  Some things are not communicated well through text.
