A solid entry! I played it twice and did not finish it. I felt like I could have drawn a map (or memorized) to be able to finish it but I don’t think I would have enjoyed that.
I think having an in-game map that tracks where you have already traveled would be really helpful to help prevent back tracking, wasting oxygen, and ultimately allowing more people to see your ending without the need to grind the game multiple times.
That said, I really enjoyed the aesthetic and style of the game. Great work!
