Questions about Plague Island.

[OmarTheInsomniac]

I just started playing plague island today and I'm currently on day 27. After i made it past day 20, This strange sound i never heard before anywhere else in the game began to play once every few days with no reason to it i could discern. It sounds like a harp/string instrument out of tune. At first i thought it maybe was signalling the arrival of some kind of special greed wave unique to this challenge but the night wave on the same day the sound plays would be a normal one. I've heard it 2 or 3 times so far. Does that sound actually mean anything or is it just meant to scare you? Also is there a reason to attack the cliff portals on plague island? It still gives me the option to attack them with my knights but it doesn't let me craft a bomb like i normally would be able to, which means i won't be able to destroy them anyways, so why does it still give you the option to send your knights out to attack them? Is there any benefit to it? If i do send them to attack a cliff portal, can the tentacle at the cliff portals damage and kill my knights/archers?

there is NO reason to send knights, and no way past the big wall at the end. i think the knight sees the wall and turns around, but the tentacle can still crush them.

the out-of-tune string sound is when one of your guys gets turned to a zombie, probably a worker cutting down trees, or maybe youve hit an edge case where the greed are coming out slightly earlier than they should and an archer is being hit.

When I last tried it the knights just stayed and attack it until they got killed, even though they can't actually damage it.

I wonder if they should just disable the option to send knights in this island.
