Knock-Knock is the latest game from Russian developer Ice Pick Lodge. That may mean nothing to you: it meant nothing to me when I first downloaded the game. Some of their previous titles did chime a little as names I’d heard now and again – Pathologic or The Void. However I soon came to understand that for those more familiar with this studio and its titles, the name presages a unique combination of inventive gameplay and jarring oddness.
Almost everything you need to know about Knock-Knock can be gleaned from one brief anecdote. About halfway through the game I spent one level wandering aimlessly around a darkened house, turning on lights and began to grow pretty bored. Then I opened a door, walked through and found myself in a dank corridor which I had to wander up and down through a series of more doors before discovering I was back at the start of the tedious level again. Infuriated, I wanted to stop. But I kept on playing.
