n this follow up to the original Mr. Do! classic, the platform-styled Mr. Do’s Castle features the eponymous clown, once again in pursuit of his favorite cherries, now held within blocks on various levels of a castle. You’ll be up against unicorn monsters who like to get in the way, but you can rely on your heavy mallet for defense. Your enemy unicorns can be destroyed in groups if they are trapped together in empty holes; these unicorns will also change color depending on their level of anger, so watch out! When you need an extra hand, unlock an additional character by utilizing the special feature of the key blocks, which come in threes. Mr. Do’s! Castle was made available for play in 1983 by Universal.
