Hi. Played this end of Stone, and saw you wanted feedback in the other thread.
The power system is pretty awkward to understand at first what's going on, especially the need to manually attack the grindstone to power things.
Additionally, the way you're using the fluid requires that power sources create it with a temperature, but the water wheels don't. e.g. the power the waterwheels generates requires the input of a grindstone to raise the temperature above 0 degrees.
There is a severe lack of usable resources on most starts, with only the desert being reliably populated enough with dead trees and small rocks, to get to the stage where you can take on regular trees and huge rocks.
I'd suggest lowering the requirement to a single or two dead trees worth to get to an axe, and no more than ten small rocks worth to get to breaking huge rocks.
In general, flint is difficult to find enough of to progress. If not for one large patch, I wouldn't have had enough in my entire starting area to get to the point of building at least one of everything. Between the scarcity of finding them, and the likely complete lack of need after stone age, I would re-think using flint.
Thinking forward, perhaps a strong reverse bias in the distance from starting point for generation would help, that way there would be a large concentration at the spawn point, and next to none outside the starting area?
