At first I wanted to go to town my self xD but then I realized I just have to brew the poison ... hard to understand tho -> am I getting it right? I have to mix "Healthy" herbs with Poisonous -> then I kill a few people -> so I can go on ?
Map is preaty big, Tilebased movement works for me. Music was a bit loude in my opinion but fititng :) a few more SFX would polish the game neat.
The herbs could use a Outline to make them better visible.
The concept is solid, reminded me alittle of Werewolf Tycoon (android game)
