I retried the game from direct download and gave it a spin. Its a nice idea but I could not figure out how to produce food or materials. I built a hut for 10 people and something that looked like a bag which was supposed to produce 25 materials but nothing ever got produced even by skipping through a few turns.
I lost after a few turns presumably as I ran out of slaves to sacrifice.
So it was a frustrating experience but I reckon if you just make it a bit clearer what is going on (like putting the name of the building type in the tooltip - I still don't know what the bag one is) then it could be a much better experience.
