I made an account just to say that the game is great, but the fire is really in need of being nerfed. I can't really enjoy the game at all because of random fires occuring and spreading unless I instantly put them out. I understand you are trying to avoid the game from being very easy, but id just build off of the task concept you have and completely replace random unexplained fires.
However I understand if you really want to use the random fires, it just definetly is way too extreme right now.
