Lady Bug (1981) is Universal's maze game in the style of Pac-Man, with twenty turnstile gates that the player swings to reshape the maze and shut out pursuing insects.
Like Pac-Man, Lady Bug has the player clear a maze — of flowers, hearts and letters — while avoiding enemies, here insects. The twist is the twenty green turnstile gates, which swing as the player passes through them and change the layout of the maze. A timer runs around the maze border, releasing up to four insects, and from level 9 every level brings four different kinds of enemy.
Kazutoshi Ueda designed the game, and Universal released it in Japan in October 1981 and worldwide in December. Coleco's version added a "Vegetable Harvest" bonus level for completing the word SPECIAL, and an Intellivision version followed in 1983.
