This game is part of the single-choice jam. It has nice presentation using a very old school Hypercard system (or similar).
You play as a member of a polar tribe in the wake of a nuclear war. Your shaman has died, and you have ritually been chosen to hunt down the murderer.
There are quite a few options at the end, making this basically a murder mystery where you choose the ending.
It is in both French and English, and I played in both. Overall, I liked it. I'm not sure if it was 'authentic' to current native tribes or invented, but the characters were, I believe, well-written and I was invested in the final choice.
