I've always wanted to enter one of these, so, here we go.
Somebody already claimed this, but more than one person can use the same topic, right? Obviously, I chose
14. Hideous sound in the dark.
Yes, I got the name wrong, but I've been saying "sounds" (plural) all week, and don't have the heart to change it now. I also took inspiration from these two:
146 Ancient lamp found in tomb—when filled and used, its light reveals strange world.
220 Bell of some ancient church or castle rung by some unknown hand—a thing . . . or an invisible Presence.
Controlled with the mouse, you move around the pitch-black screen trying to find the Invisible Church, which you search for by listening as the sound of the bell gets louder or softer while you move. But there are invisible obstacles that ALSO make sounds, which you have to avoid.
Plus, monsters. They're silent, but you can see the ones nearest you by opening your lantern (hold down the left mouse button). But they can see the light from the lantern, and will charge you as long it's lit. Release the mouse button, and they'll go back to being dormant (but will still end your game if you bump into them).
There are five difficulty levels, which have to be tackled in order.
You might not want to play this loud if somebody's sleeping in the next room.
