Loved it! The atmosphere and gameplay perfectly put you in the shoes of a seer. I'd 100% pay for a longer game. My biggest critique would be that, due to how short the submission is (compared to a full release) you don't get to see the long term consequences of your actions.
I'd also say that the dialogue system would be better if left-clicking while the chieftan was talking would auto-complete his line, but wouldn't skip it. But that's a super minor critique.
Great game!
