Great job this really improved!

A quick side note, I would also try to hint more at the environment side of things, like through dialogue or more environmental storytelling.

This is an amazing jump from your prototype! So much more fleshed out! The world you built up here is really fascinating! I love the idea of a small close knit arctic town. The characters are nice and diverse and add a good chunk of personality, exposition, and sense of direction for your game. I will say the dialogue can be a bit repetitve at times, like when I choose a dialogue option, they will say the exact same things, and when I reapproach them to talk again they will repeat what they said in the initial dialogue. So I would look into more diverse dialogue between different dialogue branches and player scenarios. I noticed a bug where the last object that I highlighted stayed highlighted even if I moved far away from it. The body and fuel worked nicely and the watch was a nice way to communicate that information and more without the player feeling too bogged down. Also this is a suggestion, you can look into it if you want. Many survival games like this are in first person, for good reason. I feel if your game was first person it would not only allow the player to relate for to the character they're playing, by literally filling their shoes, but it would also add to the protagonist clear ambiguity in this game, they're an outsider that we don't know much about, and not knowing exactly what they look like outside of vague descriptors given by the other NPCs will make that more apparent and intriguing to the player. This is a super cool game and I can't wait to see the final polish!
