If it wasn't for the mine tease, I'd have said this was a Really short game. I'm guessing there's going to be an entry level requirment to start working in the mine?
Just a few little ideas. The first is a military skill - It'd be nice to use that % boost there, like with all the other skills. The other is a clear way to see when resorces are being used up, such as iron for the blacksmith or gold for the researcher. I know it's not much, but I feel it's better to see that I'm actually producing less dew to them being used. The last idea is alittle more open ended. Having addional ways to gain the same resorce. Fishing for addional food, or having a way to divide your military into "Conquor" for land, "Pillage" for resorces and "Loot" for gold.
PS - You accidently spelt boost as bboost in the instructions (not saying my spelling is good in any way) and keep up the great work!
Indeed, it's currently set at 1,000 diamonds but this is subject to change as I have to give the game out to my hamsters yet :)
