Very well fitting on theme of course and a quite interesting small god sim to play.
I managed to unlock the 3rd power, so I don't know if there are more, but it definitely has a learning curve to it.
As for feedback: a visualization of what you would hit with your power would be very helpful. Hitting 2 grain fields with 1 rain is paramount to getting a high score and knowing you won't hit the grain field when trying to fireball a villager would also help a lot (my poor grain field !)
Great job !
