"You’re a broken robot. Fix yourself up to please Mother.

Do as you’re told.

You don’t want to let her down, and you can’t even jump yet. Let’s do something about that."

K.O.L.M. is a flash game made in the Metroidvania style in which you play as a robot trying to rebuild itself. It's also very melancholy and creepy. As you traverse the various levels, Mother begins to speak to you and as the game unfolds, she becomes increasingly mean and angry. You unravel the story of how you came to be and what happened before you woke up broken.

There is also now a sequel: K.O.L.M 2 in which you meet Father and Sister.
