Thanks for your feedback! It turns out during playtesting, that using grain for both trading and consuming is more confusing than enjoyable. So the feature was reduced to the trading aspect, which makes the game flow more smoothly.
The decisions are fixed, so you can see how different decisions affect the game. The events where added for a little bit of randomness. But I'll keep your suggestion in mind ;-)
60.000 is the first treshold for a better ending.
Good observation. I expected someone to ask why there are four advisors in the game ;-D
