according to ArmorGames: "Karoshi" is a Japanese word and means "death by overwork". In this game many things are not what you'd expect and the goal of each level is counter-intuitive: you need to die. Each stage presents a new challenge. There are several objects you can use to solve puzzles, and in later levels the game will even break it's own rules to surprise you. 50 clever levels and a boss fight at the end. We hope you have fun (killing yourself)! If you have played the Game Maker version, YES this is an official Flash version! Controls Arrows + Spacebar
