WaB. Small things

I remade the alchemy kit to work in a modular way, so adding new potions isn't huge pain anymore :D It took some time, but now it will be a lot easier to add more interesting potions in game. 

I want some of them will be helpful in the battle with specific enemies, so the player will have to figure out which potion works for which monster girl.

The second thing - now it's possible to leave Lizzy at home. She will be roaming around the house till Krowly will return for her :)
