That was cool once I figured it out, but I would have liked more information about the controls. Like a warning that it's an audio game and makes no sense without the sound on, and a note that the main thing you can interact with is kinda down in the darkness near the floor where there's mostly nothing. Because it took me three or four runs and 5-10 minutes to discover the main mechanic of the game.
Also some hints about the map icons would be nice: I figured out the whales but the other two...? I figured out through trial and error that the trapezoid with the ring on top makes gurgling noises and the... other one makes wooden clunking noises but I have no idea what they're supposed to be.
