Rendoki (Rand-o-Key) is a game where you are not in control of the controls.
The goal is to solve various puzzles as the game's controls switch without warning. If the player doesn't react fast enough, it's game over as the controls snap off, like keys being ripped off a keyboard. But just as keys can be broken, they can also be fixed. Strange that the player can't choose what key they fix, but that's ok, right?
