I fully agree with the guy who suggested having students to automate the school aspect. Just reached the Literature part and it's double bad because first off it's complete nonsense you're copying (rather than words) and secondly I keep switching up the reading of letters so I have to redo like 30% of the "words". I dread whatever gets unlocked next.
The fact that you CAN gain more resources than your capacity would indicate but that you CAN'T build something that costs more than your capacity threw me for a loop initially, especially because I didn't notice the Farm/Plantation/Mine got "we now increase your capacity" after the first purchase. Why not show that for the first build?
For the mine I wish there were moments where going back a couple of levels would be worthwhile (I'm at 27 right now), but it pretty much never works out to increasing your income despite the "x5 on break" modifier. I sure hope there's an upgrade for that modifier at some point because it feels so negligible it may as well be absent. Or a speed increasing upgrade.
