I figured it out! But no, I didn't see instructions on turning off the light.
It was an enjoyable play, but I couldn't figure out how to get past the underwater thing coming for the light house.
Oh damn. Probably a scaling issue. Sorry about that!
Any enemies you face, you'll need to shine a light on them to either stall them or make them go away. Thank you so much for playing!
Yes, it looked a little like a rock, perhaps, as it was rounded. But I thought maybe it was an underwater bomb or something.
