Thanks for the feedback! FYI the farm upgrades as you collect more revenue and eventually spawns a farmer that goes and settles a new farm with a new tractor so you will reach a point where you’re managing multiple tractors. There are different crops that are worth different amounts and those nearest the farm are worth the least, so it's beneficial to branch out.
Thought about adding purchase options but wasn’t sure it made sense thematically since you are the cloud not the farmer. I almost added a robotic scarecrow to chase off critters and a cow to eat the weeds but was worried about creating new bugs near the deadline.
The lightning is imprecise by design, as the risk you might ignite your own crops is intended as part of the challenge. I think if I were going to add some kind of progression system it would include cloud upgrades like making the lightning more precise; reducing the likelihood of entering storm mode; increased water capacity and speed etc.
