Thanks a lot for playing! Glad you liked it. :)
There's no story (at least not for now). You can create more problems for the villagers by not controlling fires, making it rain too much, and a couple of more ways. And there are a few end cases based on what you do (or don't do) like your system running out of memory.
There are a few improvements we have been thinking of to make the simulation better like adding some more commands spells and encourage players to execute different spells. Maybe we'll add those to the game later if we continue working on it.
