I don’t need hints because I’m not playing the game and I’m not planning on continuing. I’d gotten further than you think. But for context I’d already begun to explore the deeper areas when I ran into this conundrum. I built a stupidly long oxygen tube to get down there. I think the game expects you to have the sea moth first. That was one of the first moments I thought something was wrong. Then I think once I got it I couldn’t take it down there without an upgrade because I also didn’t have the moon pool unlocked. You’re talking about life pods, I never had a problem finding life pods. Those were easy and fun. It was going deeper without the sea moth and upgrades that was troublesome.
