This is not a normal clicker. It’s a psychological horror game where mechanical progress hides something dark, twisted, and unsettling. Knock on the door to earn money, upgrade your abilities, and keep knocking. It all seems simple… until it isn’t.

No price on the US Steam store for Knock Again: free, not yet for sale, or not checked yet.
