I got a couple endings, it definitely seems like there's a lot of ways the story can go. I like the kinds of control that the player has over the story, for example, on my second run I simply didn't bother swimming at the beginning of the game. I'm not precisely sure how the boxes or the fish influence the story but it definitely seems like there might be something there.
It's interesting, on reflection, that the minigame that the player has the most control over is the swimming one... the box one and the fish one are both much harder to control the outcome of.
So, this game does give me some things to think about, as well.
