I've seen a lot of people say that they were disappointed or confused that things weren't explained by the game, but I think that's the point. Things feel more Lovecraftian horror here, so the threat being kept vague and unknown is where the horror comes from which I think works well. We know just as much as June does and we're meant to feel confused and frustrated or want more explanations and moments with June's friends by the end, because June does too. The "Her" (Which I assume is the ocean itself) and the supernatural elements are not the focus of the game but they're tools to highlight June and her relationship with her friends because that's where the real story lies. I think this game is an allegory for toxic friendships and how it can be hard to lose those close to you to something like an addiction or harmful mindsets and how difficult it is to leave them even when you know they're hurting and dragging you down with them if you stay, paralleling June's talk about her cousin who had to ditch her friend group recently during the bar scene.
People say this was Studio Investigrave's weakest game so far, but I think they're viewing the game too literally when the game is obviously trying to be metaphorical. It's refreshing to see that they're leaning more towards doing subtle, quiet but still disturbing horror compared to previous games. Keep up the great work!
