Neo Mr. Do! — About this game
Neo Mr. Do! guides its clown through a field of items while monsters follow the paths he creates. Harvesting a group without pausing improves its reward, but reaching for the next item can bring a monster into the route. The thrown power ball defeats an enemy and must return before another throw is available. Heavy objects provide an alternative attack by falling onto creatures below. Collecting the field’s items or defeating the monsters changes how the area is completed, with monster clearing also opening bonus-stage opportunities.
