Our goal is to find ways to commit suicide in the stage where we are in. We collide with a spike trap, hit ourselves in the head with a block, or fire a gun in order to make a bullet bounce through a series of plates and hit us. Anything is game for killing our character.
Some of the levels are quite original and we have to solve complicated puzzles to complete to achieve our mortal objective. For example, on some levels we need to close an electrical circuit and electrocute ourselves.
Karoshi, with simple graphics, is a fun and easy to play game, but it is not for everyone.
