I led my tribe to successfully endure the winter, but only just barely!
I didn't notice any issues aside from the occasion typo or awkward phrasing. To be honest, it was quite engaging to have so much choice and also still be uncertain about the outcome. There was a good balancing of the random elements which kept the narrative feeling urgent and surprising.
While your focus was heavily on developing this system, which feels successful, I was quite impressed with the way you wove in storytelling. It gave me a lot encouragement and context to make dire choices and keep going.
Very enjoyable! I played it a couple of times to see if I could influence the ending.
