The update allows deep friendships with multiple NPCs, but romantic storylines lock after the second “heart event.” Given the game’s themes of found family and isolation in the deep, excluding poly representation feels like a missed opportunity.

Mechanics such as tandem exploration, cooperative base building, or navigating hazardous currents create shared goals that foster a sense of mutual reliance and trust.

: Reviewers praise the "effortless banter" and the way characters feel realistic and relatable rather than just "pen-and-ink creations". The inclusion of diverse romantic options and the ability to choose how to treat NPCs (e.g., gifting, chatting) adds significant replayability.
