Causality is a game about, well, causality. In it, each level is a situation that plays out before your eyes. Your goal is to use puzzle-solving abilities to change the outcome of the level, generally for the better. The mechanics are very simple, and the game teaches them to you gently. Change the direction someone goes in by moving a directional tile around, and the outcome of the level could be completely different. The game's graphical style is cute and minimalist, and the puzzles are fun. It's definitely worth playing!
