Mr. Do!'s Castle

Mr. Do!, the king of arcade clowns, is in trouble - again! This time, a pack of pesky unicorns is tromping through the walled corridors of his castle. Help Mr. Do! rid his abode of these wily, fast-moving (and deadly) creatures with a deft blow of the hammer. Sometimes a quick blow to the head is all it takes. Or maybe a well-chosen brick knocked out from above. If you can't stop the critters, you should punch a hole in the ground to slow them down. It's up to you to know when to fight or flee! The tension builds as you chase Mr. Do! through the castle's maze, collecting keys along the way. Only when Mr. Do! has collected all the keys can he unlock the castle door and give himself an extra chance to defeat those nasty critters!
