I was eagerly awaiting week 3 ever since I first finished week 2, and this absolutely did not disappoint! The rivalry between the level 3 miniboss and the player was especially creative and the new customers that you would slowly affect were just as enjoyable! I'll gladly support this (very cheap) game when its fully released knowing it will be this high quality!
I'm curious how you plan to implement new interactions and content for the upcoming weeks knowing that there is no more shelf space for potions. Will new interactions between customers be reliant on items that you obtain on the right-hand shelf, or will there be a new mechanic introduced for weeks four and five to circumvent this? This is if you even plan to have new interactions between customers to begin with, which I wouldn't blame you for not including given how much there already is! One thing that comes to mind is that a few customers seem to have enchanted weapons that don't already have a counter or seem to affect them in different ways. (IE an electric bow or a strange axe.) Maybe that could justify a new interaction or two?
My only complaint is that being titled "Tall Terror" is definitely misleading, and led to me thinking her potion was bugged until I finally tried NOT giving her the shortstack potion haha! Maybe a name change to better reflect how she's not supposed to be given that specific potion unless stated otherwise would prove helpful?
Again, this game is phenomenal and I hope that the recent censorship laws that have been going around don't affect you and your game, though I have a feeling everything is going to work out!
