Really cool concept, a farm sim with an autonomous farmer. I personally think the theme "everything has a cost" means "everything the player does has a cost or consequence". Most games usually have some resources and costs, and I think the theme has more to do with the difficult decisions that come when nothing is free. Therefore I can't really say this fits the theme that well, but it is quite technically impressive. I think the building systems you plan on implementing will make this alot better, giving the player more customizability with the farm. I also find the controls a bit difficult to work with, with the camera being a bit nauseating to control. Overall, cool stuff, I look forward to what you turn this into if you continue working on it!
