Mr. Do! — About this game
Dig tunnels through a cherry-filled playfield while monsters follow the passages you create. A magic ball can remove an enemy, but it is temporarily unavailable after a successful hit, leaving movement and falling apples important for survival. Push apples into positions where they crush pursuers without landing on you. A stage can end by eating all cherries, destroying all enemies or earning an extra life, so different routes can solve the same crowded situation. Press START, or use REMIX to change skill, sound or background detail first. Dig toward a nearby group of cherries, keep a clear retreat and test A or B’s magic ball. Push an apple only after checking what is underneath it.
