Knock Harder is a mix of puzzle game and action, a two-dimensional toy in which you find yourself in a multi-level dream and have to get out of it before time runs out. The events of the game begin to occur at the very moment when the protagonist discovers what is in a dream. He wanted to wake up, but only as it turned out, it was not a simple dream, but a multi-level one. You have to wade through the levels of dreams to get to reality. But it will not be so easy to do this, because the only way to wake up, even to get to another level of sleep, is to shoot yourself in the head and die.
