I played around with all the potions.
I know that it is not your goal but I found this game hilarious. How the doll reacts to getting dragged around, the facial expressions or bonking her with glass bottles in the head are amusing to me.
I randomly found that if you threw the bottles just right to her face, you can get the potion effect without having to drag the bottle to her. This leads to applying effects on her at top speed!
Since this is so early in development there isn't much I can say. There are a lot of things that are broken but it is understandable. Good luck in the development!
