Blast-Man Joe is set in a cave. The outline of the cave is made up of indestructible blue blocks. The background is exactly the same as the background of Super Treadmill, black with greyish circles. In each cave there is an enemy and destroyable blocks. Each cave has an exit which leads to another game. What makes Blast-Man Joe different from other games in Mega Mash is that Blast Man Joe climbs around the cave from a top-down perspective, movements being more restrictive in that levels are grid shaped and cause Joe to make long movements.
