Knock-Knock is about a hermit tormented by Vistors now available on Steam for 15% off

Knock Knock. Who's there? The game actually, and it's been released on Steam and is 15% off until October 11.

Knock-Knock is the demented brain child of Ice-Pick Lodge about a man living in a house in the woods which receives visits from "unusual guests that knock on the window inviting this strange hermit to join them in a game of hide-and-seek."

To win, he only needs to remain alive while maintaining his sanity until sunrise - and apparently approaching the Visitors head-on "is a dangerous idea."

Here' the official blurb:

"As soon as the first Visitor emerges from the forest, the countdown begins. Every passing hour brings them closer to the house, and the house's walls offer no sanctuary. Something is already inside. Something is opening the window and banging around in the kitchen. Something controls the cellar and attic. Floorboards creak softly deep in the bowels of the house.

The Visitors are well aware of your position, so you must make your rounds of the house and find the breaches that let the creatures inside while doing your best to mend them.

You may come across some useful items that might help your survival, but those items are always random and your inventory is limited to 5 slots, so your gear changes by night.

Survive until sunrise and the monsters disappear, but if they get you before the sun peeks over the horizon, well, just the idea is terrifying."

It actually sounds like a lot of fun so I may give it a go this weekend myself.
