Yeah, the trick there is to demolish everything around the fire. I was going to implement something like in the original Sim City, where you can put firemen on the map, but I didn't have time for this kind of things.
Also, you can disable disasters in the pause menu.
I saw the disable, but yeah, I was more just scratching my head wondering why my firemen weren't dashing to the blaze :)
It is really good and very polished considering the time constraints
Thanks! I'll keep this in mind if I decide to work on it a bit more in the future.
