Looking for an indie underwater steampunk game NL streamed

I have been going insane all day trying to remember what this game's called. My friend recommended me a new indie horror game called Iron Lung with nearly the same premise, but this game came at most 4 years ago. I think it might have been a sponsored segment on stream? I'm pretty sure it wasn't an NL Tries.

It was a singleplayer first person kinda horror-puzzle game where you're piloting some kind of underwater submarine or walking suit robot thing, and there's no window and you interact with the outside world with buttons in the cabin and through a radar and possibly co-ordinates on a map? I remember there being lots of restarting at the start of the game because of some puzzle or quirk with the controls that resulted in lots of game overs. The atmosphere was very grim.

It's not Subnautica, Abzu, In Other Waters, Soma, Barotrauma, Paranautical Activity, Obra Dinn, or We Need to go Deeper.

EDIT IT HAS BEEN FOUND THE GAME IS NAUTICRAWL
