Thanks for the feedback, I appreciate it.
The lack of random heat sources is intentional — in a place like Antarctica there wouldn’t realistically be shelters scattered around, and I wanted exposure and navigation to matter. Also, once you leave to complete an objective, the next task is specifically to find the base and return to it, so being able to “randomly” re-enter it wouldn’t really make sense within the flow of the game.
I do agree about the map edges though, and I’ll look into improving that.
Thanks for playing.
