Hammerin' Harry

Hammerin' Harry: Ghost Building Company is a 2D side-scrolling platformer for the Game Boy. Gameplay involves swinging the hammer to bash enemies, with specific attacks: normal swing, air poke, crouch ground strike, and overhead hammer raise for protection or stun. Players navigate haunted levels, solving platforming puzzles while fighting ghost foes. Story follows Harry rescuing his kidnapped spouse from the evil Ghost Building Company, a team of four fused ghosts that merge into a giant boss. Characters include Harry as the hammer-wielding carpenter and his wife as the victim. It stands out for its unique hammer-based combat in a ghost-themed haunted mansion setting, with large sprites and easy-to-learn mechanics adapted from the 1990 arcade original.
