Lady Bug is a conversion for Commodore 64 of the popular arcade released by Universal in 1981, similar to Pac-Man.
The game was designed by Kazutoshi Ueda, also the author of Mr. Do. Lady Bug is a maze game where the main hero is, as you can imagine, a ladybug. This little bug must eat all the food in the maze without being caught by the enemy bugs. To do that, she can use the rotating doors spread around the level, useful not only to escape but also to trap the enemies. There is also some poison around the corridor, which you must avoid, but if you can lead the other bugs there, it can be advantageous. Lady bug is a surprisingly brilliant game that requires a lot of strategies if you want to master it.
