This made me extremely uncomfortable.
Would play again. 10/10.
I don't know what they are going to do, I don't think they do anything yet. There are 4 total, they aren't very hidden. I've tried burning them, putting them in my face, putting them on my bed, giving them to the golem, putting them on the mirror, having them touch eachother, nothing happens.
So, I have a semi detailed idea here. You should be able to build axes. there would be 5 types of axes you can make customers.
I'm 100% certain this is going to be implemented, since there is a design for a better shop in the current map, and he went through the trouble of designing the shop shop you're currently using too. If he wanted a completely new shop he'd just make one new one, but he made two, you can probably upgrade shops soon :).
