The ambiance of this game is fantastic—the music changing as you explore different areas is a *chef's kiss* detail. There's something soothing about swimming games, even when you're swimming through spooky caves and the music's doing its level best to remind you of that at every turn—in the back of your mind you always know that you can turn and swim to the surface at top speed and jump out of the water like a dolphin, and that's worth a lot.
("I am not a clever man" moment: I thought the ship you start in was *your crashed ship*, and spent longer than I want to admit trying to find the radio there. Clearly, it is not there. Yet there I am, swimming through again.)
