Interesting story with nice quite exploration feel. The only thing I would criticize is that the clues led me to journal entry 6 instead of 3! It said something like: “We’ll be heading west tomorrow”, so i went straight west and found the ice wall, then had to backtrack all the way around the planet to find 3,4,5.
It was also kinda funny that his Dad was complaining about how treacherous the waters were, I’m like “No they aren’t you just re-spawn if you hit too many icebergs”
