Itch! is a casual puzzle game in which players arrange fleas of the same color in specific patterns to score points, with the challenge increasing as new fleas continuously appear and levels progress. In this game, the setting involves managing a growing population of fleas, requiring strategic placement to form lines or squares of four fleas of the same color to earn points. It stands out with its simple rules, intuitive controls, and the inclusion of three distinct game modes—Time Game, Round Game, and Puzzle Game—each offering different gameplay experiences and increasing difficulty levels.
