The audio design was superb! It really felt like a cave
I'm not sure I "got" the game. It seem to suggest I should use the right click to do the light thing when the monster is near, and maybe also turn around to see if it's their when the waves are loud? I never found them monster really - but I did found a picture of someone (the dev?), and it was a little repetitive to keep draging to move forward, and I actually wasn't sure if I was caught and the game looped back?
Still, the atmosphere is second to none, and if I saw the monster I would probably get a heart attack, so maybe it's for the best :)
